Have your STIHL dealer show you how
to operate your power tool. Observe all
applicable national, state and local laws,
safety regulations, standards and
ordinances.
WARNING
Do not lend or rent your power tool
without the instruction manual. Be sure
that anyone using it understands the
information contained in this manual.
WARNING
The use of this machine may be
hazardous. The pole pruner chain has
many sharp cutters. If the cutters contact
your flesh, they will cut you, even if the
chain is not moving.
WARNING
Do not cut any material other than wood
or wooden objects. Use your pole pruner
for limbing only.
Do not use it for other purposes, since
misuse may result in personal injury or
property damage, including damage to
the machine.
WARNING
Minors should never be allowed to use
this power tool. Bystanders, especially
children, and animals should not be
allowed in the area where it is in use.
WARNING
To reduce the risk of injury to bystanders
and damage to property, never let your
power tool run unattended. When it is
not in use (e. g. during a work break),
shut it off and make sure that
unauthorized persons do not use it.
Most of these safety precautions and
warnings apply to the use of all STIHL
pole pruners. Different models may have
different parts and controls. See the
appropriate section of your instruction
manual for a description of the controls
and the function of the parts of your
model.
Safe use of a pole pruner involves
1. the operator
2. the power tool
3. the use of the power tool.
THE OPERATOR
Physical Condition
You must be in good physical condition
and mental health and not under the
influence of any substance (drugs,
alcohol, etc.) which might impair vision,
dexterity or judgment. Do not operate
this machine when you are fatigued.
WARNING
Be alert – if you get tired, take a break.
Tiredness may result in loss of control.
Working with any power tool can be
strenuous. If you have any condition that
might be aggravated by strenuous work,
check with your doctor before operating
this machine.
WARNING
Prolonged use of a power tool (or other
machines) exposing the operator to
vibrations may produce whitefinger
disease (Raynaud's phenomenon) or
carpal tunnel syndrome.
These conditions reduce the hand's
ability to feel and regulate temperature,
produce numbness and burning
sensations and may cause nerve and
circulation damage and tissue necrosis.
All factors which contribute to
whitefinger disease are not known, but
cold weather, smoking and diseases or
physical conditions that affect blood
vessels and blood transport, as well as
high vibration levels and long periods of
Safety Precautions and
Working Techniques
Because a pole pruner is
a high-speed, fast-cut-
ting power tool with an
extended reach, special
safety precautions must
be observed to reduce
the risk of personal injury.
It is important that you
read, fully understand
and observe the following
safety precautions and
warnings. Read the
instruction manual and
the safety precautions
periodically. Careless or
improper use may cause
serious or fatal injury.
HT 102, HT 103, HT 132, HT 133

exposure to vibration are mentioned as
factors in the development of whitefinger
disease. In order to reduce the risk of
whitefinger disease and carpal tunnel
syndrome, please note the following:
Most STIHL power tools are
available with an anti-vibration
("AV") system designed to reduce
the transmission of vibrations
created by the machine to the
operator's hands. An AV system is
recommended for those persons
using power tools on a regular or
sustained basis.
Wear gloves and keep your hands
warm.
Keep the AV system well
maintained. A power tool with loose
components or with damaged or
worn AV elements will tend to have
higher vibration levels.
Maintain a firm grip at all times, but
do not squeeze the handles with
constant, excessive pressure. Take
frequent breaks.
All the above-mentioned precautions do
not guarantee that you will not sustain
whitefinger disease or carpal tunnel
syndrome. Therefore, continual and
regular users should closely monitor the
condition of their hands and fingers. If
any of the above symptoms appear,
seek medical advice immediately.
WARNING
The ignition system of the STIHL unit
produces an electromagnetic field of a
very low intensity. This field may
interfere with some pacemakers. To
reduce the risk of serious or fatal injury,
persons with a pacemaker should
consult their physician and the
pacemaker manufacturer before
operating this tool.
Proper Clothing
WARNING
To reduce the risk of injury, the operator
should wear proper protective apparel.
WARNING
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Avoid loose-fitting jackets, scarfs,
neckties, jewelry, flared or cuffed pants,
unconfined long hair or anything that
could become caught on branches,
brush or the moving parts of the unit.
Secure hair so it is above shoulder level.
THE POWER TOOL
For illustrations and definitions of the
power tool parts see the chapter on
"Main Parts".
To reduce the risk of
injury to your eyes never
operate your power tool
unless wearing goggles
or properly fitted protec-
tive glasses with
adequate top and side
protection complying with
ANSI Z 87.1 "+" (or your
applicable national stand-
ard). To reduce the risk of
injury to your face STIHL
recommends that you
also wear a face shield or
face screen over your
goggles or protective
glasses.
Wear an approved safety
hard hat to reduce the
risk of injury to your head.
Power tool noise may
damage your hearing.
Wear sound barriers (ear
plugs or ear mufflers) to
protect your hearing.
Continual and regular
users should have their
hearing checked
regularly.
Always wear heavy-duty
work gloves (e.g. made of
leather or other wear
resistant material) when
handling the machine
and the cutting tool.
Heavy-duty, nonslip
gloves improve your grip
and help to protect your
hands.
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Wear long
pants made of heavy
material to help protect
your legs. Do not wear
shorts, sandals or go
barefoot.
Good footing is very
important. Wear sturdy
boots with nonslip soles.
Steel-toed safety boots
with cut retardant inserts
are recommended.

WARNING
Never modify this power tool in any way.
Only attachments supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL model are
authorized. Although certain
unauthorized attachments are useable
with STIHL power tools, their use may,
in fact, be extremely dangerous.
If this tool is subjected to unusually high
loads for which it was not designed (e. g.
heavy impact or a fall), always check
that it is in good condition before
continuing work. Check in particular that
the fuel system is tight (no leaks) and
that the controls and safety devices are
working properly. Do not continue
operating this machine if it is damaged.
In case of doubt, have it checked by your
STIHL servicing dealer.
THE USE OF THE POWER TOOL
Transporting the Power Tool
This power tool should be carried only in
a horizontal position. Grip the shaft in a
manner that the machine is balanced
horizontally. Keep the hot muffler away
from your body and the cutting
attachment behind you.
WARNING
Accidental acceleration of the engine
can cause the chain to rotate and cause
serious injuries.
Always switch off the engine and fit the
scabbard over the cutting attachment
before transporting the power tool over
long distances. When transporting it in a
vehicle, properly secure it to prevent
turnover, fuel spillage and damage to
the unit.
Fuel
Your STIHL power tool uses an oil-
gasoline mixture for fuel (see the
chapter on "Fuel" in this instruction
manual).
WARNING
Fueling Instructions
WARNING
To reduce the risk of serious burn injury,
never attempt to refuel the unit until it
has been completely removed from the
operator.
WARNING
Fuel your machine in well-ventilated
areas, outdoors. Always shut off the
engine and allow it to cool before
refueling. Gasoline vapor pressure may
build up inside the fuel tank depending
on the fuel used, the weather or other
environmental conditions and the use of
the machine.
In order to reduce the risk of burns and
other personal injury from escaping gas
vapor and fumes, remove the fuel filler
cap on your power tool carefully so as to
allow any pressure build-up in the tank
to release slowly. Never remove the fuel
filler cap while the engine is running.
Select bare ground for fueling and move
at least 10 feet (3 m) from the fueling
spot before starting the engine. Wipe off
any spilled fuel before starting your
machine.
390BA000 KN
Gasoline is an extremely
flammable fuel. If spilled
and ignited by a spark or
other ignition source, it
can cause fire and seri-
ous burn injury or
property damage. Use
extreme caution when
handling gasoline or fuel
mix. Do not smoke or
bring any fire or flame
near the fuel or the power
tool. Note that combus-
tible fuel vapor may
escape from the fuel sys-
tem or gas can during
fueling operations.

WARNING
WARNING
To reduce the risk of fuel spillage and
fire from an improperly installed fuel cap,
correctly position and tighten the fuel
cap in the fuel tank opening.
WARNING
See also the "Fueling" chapter in this
instruction manual for additional
information.
Before Starting
Take off the chain guard (scabbard) and
inspect the pole pruner for proper
condition and operation. (See the
maintenance chart in this instruction
manual.)
WARNING
Always check your power tool for proper
condition and operation before starting,
particularly the throttle trigger, throttle
trigger lockout, stop switch and cutting
attachment. The throttle trigger must
move freely and always spring back to
the idle position. Never attempt to
modify the controls or safety devices.
WARNING
Check fuel system for leaks, especially
the visible parts, e.g., filler cap, hose
connections, manual fuel pump (only for
power tools equipped with a manual fuel
pump). To reduce the risk of personal
injury or property damage from fire, do
not start the engine if there are leaks or
damage. Have the machine repaired by
a servicing dealer before using it.
WARNING
Never operate your power tool if it is
damaged, improperly adjusted or
maintained, or not completely or
securely assembled.
WARNING
Check that the spark plug boot is
securely mounted on the spark plug – a
loose boot may cause arcing that could
ignite combustible fumes and cause a
fire.
Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, fuel mix,
grease or resin in order for you to
maintain a firm grip and properly control
your power tool.
For proper assembly of the bar and
chain follow the procedure described in
the chapter "Mounting the Bar and
Chain" of your instruction manual.
STIHL Oilomatic chain, guide bar and
sprocket must match each other in
gauge and pitch.
WARNING
Proper chain tension is extremely
important. In order to avoid improper
setting, the tensioning procedure must
be followed as described in your
manual. Always make sure the hex
nut(s) for the sprocket cover is (are)
tightened securely after tensioning the
chain. Check chain tension once more
after having tightened the nut(s). Never
start the pole pruner with the sprocket
cover loose.
Adjust carrying harness and hand grip to
suit your size before starting work.
Starting
To reduce the risk of serious personal
injury from fire, start the engine at least
10 feet (3 m) from the fueling spot,
outdoors only.
Start and operate your pole pruner
without assistance.
Your power tool is a one-person
machine. Do not allow other persons in
the general work area, even when
starting.
For specific starting instructions, see the
appropriate section of your manual.
Check for fuel leakage
while refueling and during
operation. If fuel leakage
is found, do not start or
run the machine until the
leak is fixed and any
leaked fuel has been
wiped away. Take care
not to get fuel on your
clothing. If this happens,
change your clothing
immediately.
Unit vibrations can cause
an improperly installed
fuel filler cap to loosen or
come off and spill quanti-
ties of fuel. In order to
reduce the risk of fuel
spillage and fire, tighten
the fuel filler cap by hand
as securely as possible.

Place the pole pruner on firm ground or
other solid surface in an open area or, in
the alternative, as shown in the above
picture. Maintain good balance and
secure footing.
WARNING
To reduce the risk of injury from loss of
control, do not attempt to "drop start"
your power tool. Drop starting means
pushing the machine away from the
operator, or allowing it to drop toward
the ground, while pulling on the starter
grip. This method is very dangerous
because you may lose control of the
machine.
WARNING
To reduce the risk of injury from loss of
control be absolutely sure that the guide
bar and chain are clear of you and all
other obstructions and objects, including
the ground, because when the engine
starts at starting-throttle, engine speed
will be fast enough for the clutch to
engage the sprocket and turn the chain.
Once the engine has started,
immediately blip the throttle trigger,
which should release the starting throttle
and allow the engine to slow down to
idle.
With the engine running only at idle,
attach the power tool to the spring hook
of your harness (see appropriate
chapter of this manual).
WARNING
When you pull the starter grip, do not
wrap the starter rope around your hand.
Do not let the grip snap back, but guide
the starter rope to permit the rope to
rewind properly. Failure to follow this
procedure may result in injury to your
hand or fingers and may damage the
starter mechanism.
Important Adjustments
WARNING
To reduce the risk of personal injury
from loss of control or contact with the
running cutting tool, do not use your unit
with incorrect idle adjustment. At correct
idle speed, the saw chain should not
move. For directions on how to adjust
idle speed, see the appropriate section
of your instruction manual.
If you cannot set the correct idle speed,
have your STIHL dealer check your
power tool and make proper
adjustments and repairs.
Proper chain tension is very important at
all times. Check it at regular intervals
(during work breaks and only when the
pole pruner is shut off). If the chain
becomes loose while cutting, switch off
the engine and then tighten. Never try to
tighten the chain while the engine is
running.
During Operation
Holding and Controlling the Power Tool
Always hold the unit firmly with both
hands on the handles while you are
working. Wrap your fingers and thumbs
around the handles.
Place your left hand on the shaft and
your right hand on rear grip and throttle
trigger. Left-handers must follow these
instructions, too. Keep your hands in this
position to help maintain control of your
pole pruner while working at all times.
WARNING
Never attempt to operate your power
tool with one hand. Loss of control of the
power tool resulting in serious or fatal
injury may result.

WARNING
In order to properly control your pole
pruner, always maintain good balance
and a firm foothold. Never work on a
ladder, in a tree or on any other insecure
support. Never hold the machine above
shoulder height. Do not overreach.
When working at a height above 15 feet
(4.5 m) use a lift bucket. For pole pruner
with adjustable shaft, expand the shaft
only as far as necessary for the intended
application.
WARNING
Special care must be taken in slippery
conditions (wet ground, snow) and in
difficult, overgrown terrain. Watch for
hidden obstacles such as tree stumps,
roots, rocks, holes and ditches to avoid
stumbling. For better footing, clear away
fallen branches, scrub and cuttings. Be
extremely cautious when working on
slopes or uneven ground.
WARNING
Take extreme care in wet and freezing
weather (rain, snow, ice). Put off the
work when the weather is windy, stormy
or rainfall is heavy.
Working Conditions
Operate and start your power tool only
outdoors in a well-ventilated area.
Operate it under good visibility and
daylight conditions only. Work carefully.
WARNING
WARNING
Inhalation of certain dusts, especially
organic dusts such as mold or pollen,
can cause susceptible persons to have
an allergic or asthmatic reaction.
Substantial or repeated inhalation of
dust and other airborne contaminants, in
particular those with a smaller particle
size, may cause respiratory or other
illnesses. This includes wood dust,
especially from hardwoods, but also
from some softwoods such as Western
Red Cedar. Control dust at the source
where possible. Use good work
practices, such as always cutting with a
properly sharpened chain (which
produces wood chips rather than fine
dust) and operating the unit so that the
wind or operating process directs any
dust raised by the power tool away from
the operator. Follow the
recommendations of EPA / OSHA /
NIOSH and occupational and trade
associations with respect to dust
("particulate matter"). When the
inhalation of dust cannot be
substantially controlled, i.e., kept at or
near the ambient (background) level, the
operator and any bystanders should
wear a respirator approved by NIOSH /
MSHA for the type of dust encountered.
WARNING
Breathing asbestos dust is dangerous
and can cause severe or fatal injury,
respiratory illness or cancer. The use
and disposal of asbestos-containing
products have been strictly regulated by
OSHA and the Environmental Protection
Agency. If you have any reason to
believe that you might be cutting
asbestos, immediately contact your
employer or a local OSHA
representative.
As soon as the engine is
running, this machine
generates toxic exhaust
fumes containing chemi-
cals, such as unburned
hydrocarbons (including
benzene) and carbon
monoxide, that are
known to cause respira-
tory problems, cancer,
birth defects, or other
reproductive harm and
other injuries. Some of
the gases (e. g. carbon
monoxide) may be color-
less and odorless and
can cause asphyxiation
or death very quickly. To
reduce the risk of serious
or fatal injury/illness from
inhaling toxic fumes,
never run the machine
indoors or in poorly venti-
lated locations. If exhaust
fumes become concen-
trated due to insufficient
ventilation, clear obstruc-
tions from work area to
permit proper ventilation
before proceeding and /
or take frequent breaks to
allow fumes to dissipate
before they become
concentrated.

WARNING
In order to reduce the risk of personal or
even fatal injury to bystanders from
falling objects or inadvertent contact with
the moving chain of your power tool
always keep bystanders at least 50 feet
(15 m) away when the power tool is
running.
WARNING
Even though bystanders should be kept
away from the running saw, never work
alone. Keep within calling distance of
others in case help is needed.
Stop the engine immediately if you are
approached.
DANGER
Electricity can jump from one point to
another by means of arcing. Higher
voltage increases the distance electricity
can arc. Electricity can also move
through branches, especially if they are
wet. Maintain a clearance of at least
50 feet (15 m) between the pole pruner
(including any branches it is contacting)
and any electrical line carrying live
current. Before working with less
clearance, contact your electric utility
and make sure the current is turned off.
Operating Instructions
WARNING
Do not operate your power tool using the
starting throttle position, as you do not
have control of the engine speed.
In the event of an emergency, switch off
the engine immediately by pressing the
stop switch.
WARNING
To reduce the risk of cut injuries, keep
hands and feet away from the saw
chain. Never touch a moving chain with
your hand or any other part of your body.
The saw chain continues to move for a
short period after the throttle trigger is
released (inertia effect).
Accelerating the engine while the chain
is blocked increases the load and will
cause the clutch to slip continuously.
This may result in overheating and
damage to important components (e. g.
clutch, polymer housing components) –
which can then increase the risk of injury
from the chain moving while the engine
is idling.
WARNING
If the chain becomes clogged, always
turn off the engine and make sure the
chain has stopped before cleaning.
Make sure that the saw chain does not
touch any foreign materials such as
rocks, fences, nails and the like. Such
objects may be flung off and injure the
operator or bystanders, or damage the
saw chain.
WARNING
Prior to limbing, clear the working area
from interfering limbs and brush. Then,
establish an escape area away from
where the cut limbs can fall, and remove
all obstacles.
Keep work area clear – move away
fallen limbs. Place all tools and
equipment at a safe distance from the
branches being limbed, but not in the
escape area.
WARNING
Always observe the general condition of
the tree. Look for decay and rot in the
trunk and branches. If it is rotted inside,
15m (50ft)
15m (50ft)
Your power tool is not
insulated against electric
shock. To reduce the risk
of electrocution, never
operate this power tool in
the vicinity of any wires or
cables (power, etc.)
which may be carrying
electric current.

it could snap and fall toward the operator
while being cut. Also look for broken or
dead branches which could vibrate
loose and fall on the operator. If branch
is thick or heavy, make a shallow relief
cut on the bottom of the branch before
cutting down from the top to help prevent
splitting of the branch. See chapter on
"Using the Unit".
WARNING
To reduce the risk of severe or even fatal
injury from falling objects do not cut
vertically above your body. Hold the pole
pruner at an angle of not more than 60°
from the horizontal level (see picture).
Objects may fall in unexpected
directions. Do not stand directly
underneath the limb being cut!
Watch for falling wood! As soon as the
limbed branch starts to fall, step aside
and keep a sufficient distance away from
the falling wood.
WARNING
Always pull the unit out of the cut with
the chain running to reduce the
possibility of pinching the cutting
attachment. Don't put pressure on the
pole pruner when reaching the end of a
cut. The pressure may cause the bar
and rotating chain to pop out of the cut or
kerf, go out of control and strike some
other object.
If the bar becomes pinched and caught
in the branch so that the chain can no
longer move, shut off the pole pruner
and carefully move the branch to open
the pinch and release the bar.
WARNING
If a rotating saw chain strikes a rock or
other hard object, sparks may be
created, which can ignite flammable
materials under certain circumstances.
Flammable materials can include dry
vegetation and brush, particularly when
weather conditions are hot and dry.
When there is a risk of fire or wildfire, do
not use a power tool around flammable
materials or around dry vegetation or
brush. Contact your local fire authorities
or the U.S. Forest Service if you have
any question about whether vegetation
and weather conditions are suitable for
the use of a pole pruner.
WARNING
Never modify your muffler. Any
modification could cause an increase in
heat radiation, sparks or sound level,
thereby increasing the risk of fire, burn
injury or hearing loss. You may also
permanently damage the engine. STIHL
recommends having your muffler
serviced and repaired by a STIHL
servicing dealer.
WARNING
The muffler and other parts of the engine
(e.g. fins of the cylinder, spark plug)
become hot during operation and remain
hot for a while after stopping the engine.
To reduce risk of burns, do not touch the
muffler and other parts while they are
hot. Keep the area around the muffler
clean. Remove excess lubricant and all
debris such as pine needles, branches
or leaves. Let the engine cool down
sitting on concrete, metal, bare ground
or solid wood (e.g. the trunk of a felled
tree) away from any combustible
substances.
WARNING
An improperly mounted or damaged
cylinder housing or a
damaged/deformed muffler shell may
interfere with the cooling process of the
muffler. To reduce the risk of fire or burn
injury, do not continue work with a
damaged or improperly mounted
cylinder housing or a
damaged/deformed muffler shell.
Your muffler is furnished with a spark
arresting screen designed to reduce the
risk of fire from the emission of hot
particles. Never operate your unit with a
missing or damaged spark arresting
screen. If your gas/oil mix ratio is correct
(i.e., not too rich), this screen will
normally stay clean as a result of the
heat from the muffler and need no
service or maintenance. If you
experience loss of performance and you
suspect a clogged screen, have your

muffler maintained by a STIHL servicing
dealer. Some state or federal laws or
regulations may require a properly
maintained spark arrestor for certain
uses. See the "Maintenance, Repair and
Storing" section of these Safety
Precautions. Remember that the risk of
a brush or forest fire is greater in hot or
dry conditions.
Reactive Forces
WARNING
Reactive forces may occur any time the
chain is rotating.The force used to cut
wood can be reversed and work against
the operator. If the rotating chain is
suddenly stopped by contact with any
solid object such as a branch or is
pinched, the reactive forces may occur
instantly. These reactive forces may
result in loss of control, which, in turn,
may cause personal injury. An
understanding of the causes of these
reactive forces may help you avoid the
element of surprise and loss of control.
Because of the design of the pole
pruner, the reactive forces experienced
when working with it are generally not as
severe as those encountered with a
chainsaw. Nevertheless, you should
always maintain a proper grip and good
footing to control the power tool when
you experience such forces.
The most common reactive forces are:
kickback,
pushback,
pull-in.
Kickback
Kickback may occur when the moving
saw chain near the upper quadrant of
the bar nose contacts a solid object or is
pinched.
The reaction of the cutting force of the
chain causes a rotational force on the
pole pruner in the direction opposite to
the chain movement. This may cause
the bar to move upward.
To Avoid Kickback
The best protection from kickback is to
avoid kickback situations:
1. Be aware of the location of the guide
bar nose at all times.
2. Never let the nose of the guide bar
contact any object. Do not cut limbs
with the nose of the guide bar. Be
especially careful near wire fences
and when cutting small, tough
limbs, which may easily catch the
chain.
3. Cut only one limb at a time.
A = Pull-in
Pull-in occurs when the chain on the
bottom of the bar is suddenly stopped
when it is pinched, caught or encounters
a foreign object in the wood. The
reaction of the chain pulls the pole
pruner forward.
Pull-in frequently occurs when the chain
is not rotating at full speed before it
contacts the wood.
To Avoid Pull-in
1. Be alert to forces or situations that
may cause material to pinch the
chain at the bottom of the bar.
2. Always start a cut with the chain
rotating at full speed.
B = Pushback
Pushback occurs when the chain on the
top of the bar is suddenly stopped when
it is pinched, caught or encounters a
foreign object in the wood. The reaction
of the chain may drive the pole pruner
rapidly straight back toward the

operator. Pushback frequently occurs
when the top of the bar is used for
cutting.
To Avoid Pushback
1. Be alert to forces or situations that
may cause material to pinch the
chain at the top of the bar.
2. Do not cut more than one limb at a
time.
3. Do not twist the bar when
withdrawing it from an underbuck
cut because the chain can pinch.
MAINTENANCE, REPAIR AND
STORING
Maintenance, replacement, or repair of
the emission control devices and
systems may be performed by any
nonroad engine repair establishment or
individual. However, if you make a
warranty claim for a component which
has not been serviced or maintained
properly, STIHL may deny coverage.
WARNING
STIHL recommends the use of STIHL
replacement parts for maintenance and
repair. Use of parts manufactured by
others may be extremely dangerous and
could result in serious or fatal injury.
Strictly follow the maintenance and
repair instructions in the appropriate
sections of this instruction manual.
Please refer to the maintenance chart in
this manual.
WARNING
Always stop the engine and make sure
that the chain is stopped before doing
any maintenance or repair work or
cleaning the power tool. Do not attempt
any maintenance or repair work not
described in this instruction manual.
STIHL recommends that you have such
work performed by your STIHL servicing
dealer.
Wear gloves when handling or
performing maintenance on the cutting
attachment.
WARNING
To reduce the risk of fire and burn injury
or property damage, use only spark
plugs authorized by STIHL. Always
press spark plug boot snugly onto spark
plug terminal of the proper size. (Note: If
terminal has detachable SAE adapter
nut, it must be securely attached.) A
loose connection between spark plug
terminal and the ignition wire connector
in the boot may create arcing that could
ignite combustible fumes and cause a
fire. Keep the spark plug clean and
make sure the ignition lead is in good
condition.
WARNING
Never test the ignition system with the
ignition wire boot removed from the
spark plug or with a removed spark plug,
since uncontained sparking may cause
a fire.
WARNING
Do not operate your power tool if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Your muffler is equipped with a spark-
arresting screen to reduce the risk of
fire; never operate your power tool if the
screen is missing, damaged or clogged.
Remember that the risk of a brush or
forest fire is greater in hot or dry
weather.
In California, it is a violation of § 4442 or
§ 4443 of the Public Resources Code to
use or operate gasoline-powered tools
on forest-covered, brush-covered or
grass-covered land unless the engine’s
exhaust system is equipped with a
complying spark arrester that is
maintained in effective working order.
The owner/operator of this product is
responsible for properly maintaining the
spark arrester. Other states or
governmental entities/agencies, such as
the U.S. Forest Service, may have
similar requirements. Contact your local
fire agency or forest service for the laws
or regulations relating to fire protection
requirements.
WARNING
Keep the chain, bar and sprocket clean;
replace worn sprockets or chains. Keep
the chain sharp. You can spot a dull
chain when easy-to-cut wood becomes
hard to cut or burn marks appear on the
wood. Keep chain at proper tension.
Tighten all nuts, bolts and screws except
the carburetor adjustment screws after
each use.

Preparations
N Wear suitable protective clothing,
observe safety precautions.
N Adjust telescoping shaft to the
required length (HT 103, HT 133
only).
N Start the engine.
N Put on the shoulder strap.
Cutting Sequence
To allow branches to free fall, always cut
the lower branches first. Prune heavy
branches (large diameter) in several
controllable pieces.
WARNING
Never stand directly underneath the
branch you are cutting – be wary of
falling branches. Note that a branch may
spring back at you after it hits the ground
– risk of injury.
Disposal
Do not throw cuttings into the garbage
can – they can be composted.
Working Techniques
Hold the control handle with your right
hand, and the shaft with your left hand.
Your left arm should be extended to the
most comfortable position.
HT 102, HT 132
Always hold the shaft with your left hand
in the area of the handle hose.
The shaft should always be held at an
angle of 60° or less.
The least tiring working position is a tool
angle of 60°.
Any lesser angle may be used to suit the
situation.

Cross-cut
To avoid pinching the bar in the cut,
position the cutting attachment with the
housing against the branch and then
perform the cross-cut from the top
downwards.
Relieving cut
To avoid tearing the bark on thick
branches, always start by performing a
relieving cut (1) on the underside of the
branch.
N To do this, apply the cutting
attachment and pull it across the
bottom of the branch in an arc as far
as the bar nose.
N Perform the cross cut (2) – position
the bar with the housing against the
branch.
Flush-cutting thick branches
If branch diameter is more than
10 cm (4 in), first
N perform undercut (3) and then
cross-cut at a distance of about
20 cm/8 in (A) from the final cut.
Then carry out the flush-cut (4),
starting with a relieving cut and
finishing with a cross-cut.
Cutting above obstacles
The machine's long reach makes it
possible to prune branches that are
overhanging obstacles, such as rivers or
lakes. The tool angle in this case
depends on the position of the branch.
Cutting from a lift bucket
The machine's long reach enables
cutting to be performed next to the trunk
without the risk of the lift bucket
damaging other branches. The tool
angle in this case depends on the
position of the branch.

A cutting attachment consists of the saw
chain, guide bar and chain sprocket.
The cutting attachment that comes
standard is designed to exactly match
the pole pruner.
The pitch (t) of the saw chain (1),
chain sprocket and the nose
sprocket of the Rollomatic guide bar
must match.
The drive link gauge (2) of the saw
chain (1) must match the groove
width of the guide bar (3).
If non-matching components are used,
the cutting attachment may be damaged
beyond repair after a short period of
operation.
Chain scabbard
Your pole pruner comes standard with a
chain scabbard that matches the cutting
attachment.
If you use guide bars of different lenghts
on the pole pruner, the length of the
chain scabbard must be matched to the
guide bar to reduce the risk of injury. It
should cover the full length of the guide
bar.
The length of the matching guide bars is
marked on the side of the chain
scabbard.
Removing the Chain Sprocket Cover
N Unscrew the nut and remove the
chain sprocket cover.

This engine is certified to operate on
unleaded gasoline and the STIHL two-
stroke engine oil at a mix ratio of 50:1.
Your engine requires a mixture of high-
quality gasoline and two-stroke air
cooled engine oil.
Use mid-grade unleaded gasoline with a
minimum octane rating of 89 ((R+M)/2)
and no more than 10% ethanol content.
Fuel with an octane rating below 89 may
increase engine temperatures. This, in
turn, increases the risk of piston seizure
and damage to the engine.
The chemical composition of the fuel is
also important. Some fuel additives not
only detrimentally affect elastomers
(carburetor diaphragms, oil seals, fuel
lines, etc.), but magnesium castings and
catalytic converters as well. This could
cause running problems or damage the
engine. For this reason STIHL
recommends that you use only quality
unleaded gasoline!
Gasoline with an ethanol content of
more than 10% can cause running
problems and major damage in engines
and should not be used.
For further details, see
www.STIHLusa.com/ethanol
The ethanol content in gasoline affects
engine speed – it may be necessary to
readjust the carburetor if you use fuels
with various ethanol contents.
WARNING
To reduce the risk of personal injury
from loss of control and / or contact with
the running cutting tool, do not use your
unit with incorrect idle adjustment. At
correct idle speed, the cutting tool
should not move.
If your power tool´s idle speed is
incorrectly adjusted, have your
authorized STIHL servicing dealer
check your machine and make the
proper adjustments and repairs.
The idle speed and maximum speed of
the engine change if you switch from a
fuel with a certain ethanol content to
another fuel with a much higher or lower
ethanol content.
This problem can be avoided by always
using fuel with the same ethanol
content.
To ensure the maximum performance of
your STIHL engine, use a high quality 2-
cycle engine oil, such as STIHL 2-cycle
engine oils. STIHL 2-cycle engine oils
are specially designed for STIHL
engines. To help your engine run
cleaner and reduce harmful carbon
deposits, STIHL recommends using
STIHL HP Ultra 2-cycle engine oil, or
use an equivalent high quality 2-cycle
engine oil.
To meet the requirements of EPA and
CARB we recommend to use STIHL HP
Ultra oil or equivalent.
Do not use BIA or TCW rated (two-
stroke water cooled) mix oils or other
mix oils that state they are for use in both
water cooled and air cooled engines
(e.g., outboard motors, snowmobiles,
chain saws, mopeds, etc.).
Take care when handling gasoline.
Avoid direct contact with the skin and
avoid inhaling fuel vapor. When filling at
the pump, first remove the container
from your vehicle and place the
container on the ground before filling. To
reduce the risk of sparks from static
discharge and resulting fire and/or
explosion, do not fill fuel containers that
are sitting in or on a vehicle or trailer.
The container should be kept tightly
closed in order to limit the amount of
moisture that gets into the mixture.
The machine’s fuel tank should be
cleaned as necessary.
STIHL MotoMix
STIHL recommends the use of STIHL
MotoMix. STIHL MotoMix has a high
octane rating and ensures that you
always use the right gasoline/oil mix
ratio.
STIHL MotoMix uses STIHL HP Ultra
two-stroke engine oil suited for high
performance engines.
For further details, see
www.STIHLusa.com/ethanol
Fuel mix ages
If not using STIHL MotoMix, only mix
sufficient fuel for a few days of work, not
to exceed 30 days of storage. Store in
approved fuel-containers only. When
mixing, pour oil into the container first,
and then add gasoline. Close the
container and shake it vigorously by
hand to ensure proper mix of oil and
gasoline.

For automatic and reliable lubrication of
the chain and guide bar – use only an
environmentally compatible quality
chain and bar lubricant. Rapidly
biodegradable STIHL BioPlus is
recommended.
NOTICE
Biological chain oil must be resistant to
aging (e.g. STIHL BioPlus), since it will
otherwise quickly turn to resin. This
results in hard deposits that are difficult
to remove, especially in the area of the
chain drive and chain. It may even cause
the oil pump to seize.
The service life of the chain and guide
bar depends on the quality of the
lubricant. It is therefore essential to use
only a specially formulated chain
lubricant.
WARNING
Do not use waste oil. Renewed contact
with waste oil can cause skin cancer.
Moreover, waste oil is environmentally
harmful.
NOTICE
Waste oil does not have the necessary
lubricating properties and is unsuitable
for chain lubrication.
NOTICE
A full chain oil tank is sufficient for only
half a tankful of fuel. Check the oil level
regularly during cutting work. Never
allow the oil tank to run dry.
Preparations
N Thoroughly clean the tank cap and
the area around it to ensure that no
dirt falls into the tank.
N Position the machine so that the
tank cap faces up.
Opening
N Raise the grip until it is upright.
N Turn the cap counterclockwise

Cutting effortlessly with a correctly
sharpened chain
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
Do not work with a dull or damaged
chain as it will increase the physical
effort required, produce unsatisfactory
results and a higher rate of wear.
N Clean the chain.
N Check the chain for cracks in the
links and damaged rivets.
N Replace any damaged or worn
parts of the chain and match the
new parts to the shape and size of
the original parts.
Carbide-tipped saw chains (Duro) are
particularly wear resistant. STIHL
recommends you have your chain
resharpened by a STIHL servicing
dealer.
WARNING
It is absolutely essential to comply with
the angles and dimensions specified
below. If the saw chain is incorrectly
sharpened and in particular if the depth
gauge is set too low – there is an
increased risk of kickback, with resulting
risk of injury.
The saw chain cannot be locked in place
on the guide bar. Therefore, it is best to
remove the chain from the bar and
resharpen it on a workshop sharpening
tool (FG 2, HOS, USG).
Chain pitch
The chain pitch (a) is marked on the
depth gauge end of each cutter.
Select file diameter according to chain
pitch – see table “Sharpening Tools”.
You must observe certain angles when
resharpening the chain cutter.
Filing and side plate angles
A Filing angle
STIHL saw chains are sharpened to a
filing angle of 30°. Exceptions are
ripping chains with a filing angle of 10°.
Ripping chains have an X in their
designations.
B Side plate angle
The correct side plate angle is obtained
automatically if you use the prescribed
file holder and file diameter.
The angles must be the same on all
cutters. If the angles are uneven: Chain
will run roughly, not in a straight line,
wear quickly and finally break.
File holder
N Use a file holder
A file holder must be used for manual
resharpening (see table "Sharpening
Tools"). The correct filing angles are
marked on the file holder.

Use only special saw chain sharpening
files. Other files have the wrong shape
and cut.
For checking angles
Use a STlHL filing gauge (special
accessory, see table "Sharpening
Tools"). This is a universal tool for
checking the filing and side plate angles,
depth gauge setting, cutter length and
groove depth. It also cleans the guide
bar groove and oil inlet holes.
File correctly
N Select sharpening tools according
to chain pitch.
N If you use an FG 2, HOS or USG
sharpener: Remove the chain from
the bar and sharpen according to
the instructions supplied with the
tool.
N Clamp the bar in a vise if necessary.
N Sharpen the chain frequently, take
away as little metal as possible –
two or three strokes of the file are
usually enough.
N Hold the file horizontally (at a right
angle to the side of the guide bar)
and file according to the angles
marked on the file holder. Rest the
file holder on the top plate and depth
gauge.
N Always file from the inside to the
outside of the cutter.
N The file only sharpens on the
forward stroke – lift the file off the
cutter on the backstroke.
N Avoid touching the tie straps and
drive links with the file.
N Rotate the file at regular intervals
while filing to avoid one-sided wear.
N Use a piece of hardwood to remove
burrs from the cutting edge.
N Check angles with the filing gauge.
All cutters must be the same length.
If the cutters are not the same length,
they will have different heights. This
makes the chain run roughly and can
cause it to break.
N Find the shortest cutter and then file
all other cutters back to the same
length. It is best to have this work
done by a servicing dealer on an
electric grinder.
Depth gauge setting
The depth gauge determines the height
at which the cutter enters the wood and
thus the thickness of the chip removed.
a Specified distance or setting
between depth gauge and cutting
edge.
This setting may be increased by 0.2
mm (0.008") for cutting softwood in the
mild weather season – no frost.

Lowering depth gauges
The depth gauge setting is reduced
when the chain is sharpened.
N Use a filing gauge to check the
setting every time you sharpen the
chain.
N Place a filing gauge (1) that
matches the chain pitch on the
chain and press it against the cutter
– if the depth gauge projects from
the filing gauge, the depth gauge
has to be lowered.
Saw chains with humped drive link (2)
upper part of humped drive link (2) (with
service mark) is lowered along with the
depth gauge.
WARNING
The other parts of the humped drive link
must not be filed since this may increase
the kickback tendency of the power tool.
N File down the depth gauge until it is
level with the filing gauge.
N File the top of the depth gauge
parallel to the stamped service
marking (see arrow) – but do not
lower the highest point of the depth
gauge in this process.
WARNING
The kickback tendency of the machine is
increased if the depth gauges are too
low.
N Place the filing gauge on the chain
the highest point of the depth gauge
must be level with the filing gauge.
N After sharpening, clean the chain
thoroughly, remove filings or
grinding dust – lubricate the chain
thoroughly.
N Before a long out-of-service period,
clean the chain and store it in a well-
oiled condition.

During Break-In Period
A factory-new machine should not be
run at high revs (full throttle off load) for
the first three tank fillings. This avoids
unnecessary high loads during the
break-in period. As all moving parts
have to bed in during the break-in
period, the frictional resistances in the
engine are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
During Operation
NOTICE
Do not make the mixture leaner to
achieve an apparent increase in power
this could damage the engine – see
"Adjusting the Carburetor".
Check chain tension frequently
A new chain has to be retensioned more
often than one that has been in use for
some time.
Chain cold
Tension is correct when the chain fits
snugly against the underside of the bar
and can still be pulled along the bar by
hand. Retension if necessary – see
"Tensioning the Saw Chain".
Chain at operating temperature
The chain stretches and begins to sag.
The drive links must not come out of the
bar groove – the chain may otherwise
jump off the bar. Retension the chain –
see "Tensioning the Saw Chain".
After long period of full-throttle operation
Allow engine to run for a short while at
idle speed so that engine heat can be
dissipated by the flow of cooling air. This
protects engine-mounted components
(ignition, carburetor) from thermal
overload.
After Finishing Work
N Slacken off the chain if you have
retensioned it at operating
temperature during cutting work.
NOTICE
Always slacken off the chain after
finishing work. The chain contracts as it
cools down. If it is not slackened off, it
can damage the gear shaft and
bearings.
Storing your saw for a short period
Wait for the engine to cool down. Drain
the fuel tank. Store the machine in a dry
location. Check the tightness of all
accessible screws and nuts (not
adjusting screws) at regular intervals
and retighten if necessary.
Storing for a long period
See chapter on "Storing the Machine"
N Turn the bar over every time you
sharpen the chain and every time
you replace the chain – this helps
avoid one-sided wear, especially at
the nose and underside of the bar.
N Regularly clean the oil inlet hole (1),
the oilway (2) and the bar
groove (3).
N Measure the groove depth with the
scale on the filing gauge (special
accessory) – in the area used most
for cutting.
If groove depth is less than specified:

The drive link tangs will otherwise
scrape along the bottom of the groove –
the cutters and tie straps will not ride on
the bar rails.
Filters have an average life of more than
a year. Do not remove the filter cover or
replace the air filter as long as there is no
noticeable loss of power.
If there is a noticeable loss of engine
power
N Turn the choke knob to g.

The carburetor has been set at the
factory to provide an optimum fuel-air
mixture under most operating
conditions.
Adjusting Idle Speed
Engine stops while idling
N Warm up the engine for about
3 minutes.
N Turn the idle speed screw (LA)
slowly clockwise until the engine
runs smoothly – the saw chain must
not rotate.
Chain rotates when engine is idling
N Turn the idle speed screw (LA)
counterclockwise until the chain
stops running and then turn the
screw another 1/2 to 3/4 turn in the
same direction.
WARNING
If the chain continues moving when the
engine is idling, have your power tool
checked and repaired by your servicing
dealer.
N If the engine is down on power,
check the spark arresting screen in
the muffler.
N Wait for the muffler to cool down.
N Take out the screw (4).
N Lift the spark arresting screen (5)
and pull it out.
N Clean the spark arresting
screen (5). If the screen is damaged
or heavily carbonized, install a new
one.
N Refit the spark arresting screen (5).
N Insert the screw (4) and tighten it
down firmly.
If the engine is down on power, difficult
to start or runs poorly at idling speed,
first check the spark plug.
Install a new spark plug after approx.
100 operating hours or earlier if the
electrodes are badly eroded/corroded.
The wrong fuel mix (too much engine oil
in the gasoline), a dirty air filter and
unfavorable running conditions (mostly
at part throttle etc.) affect the condition
of the spark plug. These factors cause
deposits to form on the insulator nose
which may degrade performance.
Removing the Spark Plug
N Remove the cover (1).
N Pull off the spark plug boot (2).
N Unscrew the spark plug (3).

For periods of 3 months or longer
N Drain and clean the fuel tank in a
well ventilated area.
N Dispose of fuel properly in
accordance with local
environmental requirements.
N Run the engine until the carburetor
is dry – this helps prevent the
carburetor diaphragms sticking
together.
N Remove the saw chain and guide
bar, clean them and spray with
corrosion inhibiting oil.
N Thoroughly clean the machine pay
special attention to the cylinder fins
and air filter.
N If you use a biological chain and bar
lubricant, e.g. STIHL BioPlus,
completely fill the chain oil tank.
N Store the machine in a dry, high or
locked location, out of the reach of
children and other unauthorized
persons.
N Remove the chain sprocket cover,
chain and guide bar.
Replace the chain sprocket:
after using two saw chains or
sooner
if the wear marks (a) on the sprocket
are deeper than approx. 0.5 mm
(0.02 in) since this would reduce the
life of the chain. You can use a
gauge (special accessory) to check
the depth of the wear marks.
It is best to use two saw chains in
rotation with one sprocket.
STIHL recommends the use of original
STIHL chain sprockets.
The chain sprocket is driven via a friction

mienta de corte
motorizada de gran velo-
cidad y de alcance muy
largo, es necesario tomar
medidas especiales de
seguridad para reducir el
riesgo de lesiones.
Es importante que usted
lea, comprenda bien y
respete las siguientes
advertencias y medidas
de seguridad. Lea el
manual de instrucciones
y las precauciones de

ADVERTENCIA
El uso prolongado de una herramienta
motorizada (u otras máquinas) expone
al operador a vibraciones que pueden
provocar el fenómeno de Raynaud
(dedos blancos) o el síndrome del túnel
carpiano.
Estas condiciones reducen la capacidad
de las manos de sentir y regular la
temperatura, producen entumecimiento
y ardor y pueden provocar trastornos
nerviosos y circulatorios, así como
necrosis de los tejidos.
No se conocen todos los factores que
contribuyen a la enfermedad de
Raynaud, pero el clima frío, el fumar y
las enfermedades o condiciones físicas
que afectan los vasos sanguíneos y la
circulación de la sangre, como asimismo
los niveles altos de vibración y períodos
prolongados de exposición a la
vibración son mencionados como
factores en el desarrollo de la
enfermedad de Raynaud. Por lo tanto,
para reducir el riesgo de la enfermedad
de dedos blancos y del síndrome del
túnel carpiano, sírvase notar lo
siguiente:
La mayor parte de las herramientas
motorizadas de STIHL se ofrecen
con un sistema antivibración ("AV")
cuyo propósito es reducir la
transmisión de las vibraciones
creadas por la máquina a las manos
del operador. Se recomienda el uso
del sistema AV a aquellas personas
que utilizan herramientas
motorizadas en forma constante y
regular.
Use guantes y mantenga las manos
abrigadas.
Mantenga el sistema AV en buen
estado. Una herramienta
motorizada con los componentes
flojos o con elementos AV dañados
o desgastados también tendrá
tendencia a tener niveles más altos
de vibración.
Agarre firmemente los mangos en
todo momento, pero no los apriete
con fuerza constante y excesiva.
Tómese descansos frecuentes.
Todas las precauciones antes
mencionadas no le garantizan que va a
estar totalmente protegido contra la
enfermedad de Raynaud o el síndrome
del túnel carpiano. Por lo tanto, los
operadores constantes y regulares
deben revisar con frecuencia el estado
de sus manos y dedos. Si aparece
alguno de los síntomas arriba
mencionados, consulte inmediatamente
al médico.
ADVERTENCIA
El sistema de encendido de la máquina
STIHL produce un campo
electromagnético de intensidad muy
baja. El mismo puede interferir con
algunos tipos de marcapasos. Para
reducir el riesgo de lesiones graves o
mortales, las personas portadoras de
marcapasos deben consultar a sus
médicos y al fabricante del marcapasos
antes de usar esta máquina.
Vestimenta adecuada
ADVERTENCIA
Para reducir el riesgo de lesiones el
operador debe usar el equipo protector
adecuado.
ADVERTENCIA
Esté especialmente alerta y tenga
cuidado cuando se usa protectores de
oídos, ya que los mismos reducen la
posibilidad de oír señales de
advertencia (gritos, alarmas, etc.).
Para reducir el riesgo de
lesionarse los ojos,
nunca maneje la herra-
mienta motorizada si no
tiene puestas gafas o
anteojos de seguridad
bien ajustados con una
protección adecuada en
las partes superior y late-
ral que satisfagan la
norma ANSI Z 87.1 "+" (o
la norma nacional corres-
pondiente). Para reducir
el riesgo de lesionarse la
cara, STIHL recomienda
usar también una careta
o protector facial ade-
cuado sobre las gafas o
anteojos de seguridad.
Use un casco aprobado
para reducir el riesgo de
lesionarse la cabeza.
El ruido de la herramienta
motorizada puede dañar
los oídos. Siempre use
amortiguadores del ruido
(tapones u orejeras) para
protegerse los oídos. Los
usuarios constantes y
regulares deben some-
terse con frecuencia a un
examen o control
auditivo.

Evite el uso de chaquetas sueltas,
bufandas, corbatas, joyas, pantalones
acampanados o con vueltas, pelo largo
suelto o cualquier cosa que pueda
engancharse en las ramas, matorrales o
piezas en movimiento de la máquina.
Sujétese el pelo de modo que quede
sobre los hombros.
LA HERRAMIENTA MOTORIZADA
Para las ilustraciones y definiciones de
los componentes de la herramienta
motorizada, vea el capítulo sobre
"Piezas principales".
ADVERTENCIA
Nunca modifique, de ninguna manera,
esta herramienta motorizada. Utilice
únicamente los accesorios y repuestos
suministrados por STIHL o
expresamente autorizados por STIHL
para usarse con el modelo específico de
STIHL. Si bien es posible conectar a la
herramienta motorizada de STIHL
ciertos accesorios no autorizados, su
uso puede ser, en la práctica,
extremadamente peligroso.
Si la máquina experimenta cargas
excesivas para las cuales no fue
diseñada (por ejemplo, impactos
severos o una caída), siempre
asegúrese que la máquina está en
buenas condiciones antes de seguir con
el trabajo. Inspeccione específicamente
la integridad del sistema de combustible
(ausencia de fugas), y asegúrese de
que los controles y dispositivos de
seguridad funcionen como corresponde.
No siga manejando esta máquina si está
dañada. En caso de dudas, pida que el
concesionario de servicio de STIHL la
revise.
USO DE LA HERRAMIENTA
MOTORIZADA
Transporte de la herramienta
motorizada
Esta herramienta motorizada puede
acarrearse solamente en posición
horizontal. Agarre el eje de una manera
que mantenga la máquina equilibrada
horizontalmente. Mantenga el
silenciador caliente lejos de su cuerpo y
el accesorio de corte detrás de usted.
ADVERTENCIA
La aceleración accidental del motor
puede causar la rotación de la cadena y
lesiones graves.
Siempre apague el motor y coloque la
funda sobre el accesorio de corte antes
de transportar la herramienta
motorizada por una distancia
considerable. Cuando transporte la
máquina en un vehículo, sujétela
firmemente para impedir su vuelco, el
derrame de combustible y el daño a la
máquina.
Siempre use guantes
gruesos (por ejemplo,
fabricados de cuero u
otro material resistente al
desgaste) cuando mani-
pule la máquina y la
herramienta de corte. Los
guantes gruesos y anti-
deslizantes mejoran el
manejo y ayudan a prote-
ger las manos.
La ropa debe ser de con-
fección fuerte y ajustada,
pero no tanto que impida
la completa libertad de
movimiento. Use pantalo-
nes largos hechos de un
material grueso para pro-
tegerse las piernas. No
use pantalones cortos,
sandalias o pies
descalzos.
Es muy importante tener
una buena superficie de
apoyo para los pies. Pón-
gase botas gruesas con
suela antideslizante.
Recomendamos las
botas de seguridad con
puntera de acero con
insertos reforzados resis-
tentes a cortaduras.

Combustible
La herramienta motorizada STIHL utiliza
una mezcla de aceite-gasolina como
combustible (vea el capítulo
"Combustible" en el manual del
propietario).
ADVERTENCIA
Instrucciones para el llenado de
combustible
ADVERTENCIA
Para reducir el riesgo de lesiones
graves causadas por quemaduras,
nunca intente abastecer la máquina con
combustible sin que el operador se haya
despojado de la misma.
ADVERTENCIA
Cargue de combustible su máquina en
lugares al aire libre bien ventilados.
Siempre apague el motor y deje que se
enfríe antes de llenar de combustible.
Dependiendo del combustible utilizado,
de las condiciones climáticas o de
medio ambiente, es posible que se
forme vapor de gasolina a presión
dentro del tanque de combustible.
Para reducir el riesgo de quemaduras,
así como otras lesiones corporales
ocasionadas por los escapes de vapor
de gasolina y otras emanaciones, quite
la tapa de llenado de combustible de la
herramienta motorizada
cuidadosamente de modo que la
presión que se pueda haber acumulado
en el depósito se disipe lentamente.
Nunca quite la tapa de llenado de
combustible mientras el motor esté
funcionando.
Elija una superficie despejada para
llenar el tanque y aléjese 3 m (10 pies)
por lo menos del lugar en que lo haya
llenado antes de arrancar el motor.
Limpie todo el combustible derramado
antes de arrancar la máquina.
ADVERTENCIA
ADVERTENCIA
Para reducir el riesgo de derramar
combustible y provocar un incendio
debido a una tapa de combustible mal
instalada, coloque la tapa en la posición
correcta y apriétela en la boca de
llenado del tanque.
ADVERTENCIA
La gasolina es un com-
bustible muy inflamable.
Si se derrama y arde a
causa de una chispa u
otra fuente de ignición,
puede provocar un incen-
dio y quemaduras graves
o daños a la propiedad.
Tenga sumo cuidado
cuando manipule gaso-
lina o la mezcla de
combustible. No fume
cerca del combustible o
la herramienta motori-
zada, ni acerque ningún
fuego o llama a ellos.
Puede escapar vapor
inflamable del sistema de
combustible o de la lata
de gasolina mientras
llena el tanque.
Compruebe que no exis-
ten fugas de combustible
mientras llena el tanque y
durante el funciona-
miento de la máquina. Si
detecta alguna fuga de
combustible, no arran-
que la máquina ni lo haga
funcionar sin antes repa-
rar la fuga y limpiar el
combustible vertido.
Tenga cuidado de no
mancharse la ropa con
combustible. Si la man-
cha, cámbiesela
inmediatamente.
Las vibraciones de la
máquina pueden aflojar
una tapa de combustible
que ha quedado mal ins-
talada, o simplemente
soltarla y derramar com-
bustible. Para reducir el
riesgo de derrames e
incendio, apriete la tapa
de llenado de combusti-
ble a mano tan
firmemente como sea
posible.

"Combustible" de este Manual de
instrucciones para obtener información
adicional.
Antes de arrancar
Quite el protector de la cadena (la
funda) e inspeccione el podador de
varilla para verificar que está en buenas
condiciones de funcionamiento.
(Consulte la tabla de mantenimiento en
este manual de instrucciones.)
ADVERTENCIA
Siempre revise la herramienta
motorizada para comprobar que está en
buenas condiciones y que funciona
correctamente antes de arrancarla, en
particular el gatillo de aceleración y su
bloqueo, el interruptor de parada y la
herramienta de corte. El gatillo de
aceleración debe moverse libremente y
siempre debe regresar a la posición de
marcha en vacío por la acción de
resorte. Nunca intente modificar los
controles o los dispositivos de
seguridad.
ADVERTENCIA
Revise el sistema de combustible en
busca de fugas, especialmente las
partes visibles, por ejemplo, la tapa de
llenado, conexiones de mangueras y la
bomba de combustible manual
(únicamente para herramientas
motorizadas equipadas con una bomba
de combustible de mano). Para evitar
los riesgos de lesiones personales o
daños a la propiedad causados por los
incendios, no arranque el motor si se
observan fugas o daños. Solicite al
concesionario que repare la máquina
antes de usarla.
ADVERTENCIA
No maneje nunca una herramienta
motorizada que esté dañada, mal
ajustada o mantenida o que no fue
armada completa y debidamente.
ADVERTENCIA
Asegúrese de que el casquillo de la
bujía esté firmemente colocado – un
casquillo suelto puede crear un arco
voltaico y encender los vapores del
combustible, provocando un incendio.
Mantenga los mangos limpios y secos
en todo momento; es particularmente
importante mantenerlos libres de
humedad, aceite, combustible, grasa o
resinas para garantizar que la máquina
pueda empuñarse firmemente para
mantenerla bajo control seguro.
Para el armado de la espada y la
cadena, siga el procedimiento descrito
en el capítulo "Montaje de la espada y la
cadena" del manual de instrucciones.
La cadena Oilomatic, la espada y el
piñón STIHL deben coincidir entre sí en
cuanto a calibre y paso.
ADVERTENCIA
La tensión adecuada de la cadena es
extremadamente importante. Para
evitar el ajuste inadecuado, ejecute los
procedimientos de tensado tal como se
describen en su manual. Siempre
asegúrese que la tuerca o tuercas
hexagonales para la cubierta del piñón
quedan firmemente apretadas después
de tensar la cadena. Compruebe la
tensión de la cadena una vez más
después de apretar la tuerca o las
tuercas. Nunca arranque el podador de

personales graves causadas por los
incendios, arranque el motor al aire
libre, por lo menos 3 m (10 pies) del
lugar en que lo haya llenado.
Ponga en marcha y maneje el podador
de varilla sin ayuda de nadie.
Su herramienta motorizada es una
máquina que debe ser manejada por
solamente una persona. No deje que
otras personas estén en el lugar de
trabajo, aun durante el arranque.
Para las instrucciones específicas de
arranque, vea la sección
correspondiente en el manual del
usuario.
Coloque el podador de varilla sobre
suelo firme u otra superficie dura en una
zona despejada, o en la posición

alternativa mostrada en la ilustración
anterior. Mantenga el equilibrio y elija un
buen punto de apoyo para los pies.
ADVERTENCIA
Para reducir el riesgo de sufrir lesiones
causadas por la pérdida de control, no
intente arrancar el motor de la
herramienta "por lanzamiento". Arrancar
por lanzamiento significa que el
operador empuje la máquina lejos, o
que el operador permite que la máquina
caiga hacia el suelo al hacer tirar el
mango de arranque. Este método es
muy peligroso porque usted puede
perder el control de la máquina.
ADVERTENCIA
Para reducir el riesgo de lesiones
debido a la pérdida de control, esté
absolutamente seguro de que la espada
y la cadena se encuentran lejos de su
cuerpo y de todas las obstrucciones y
objetos, incluido el suelo, porque al
arrancar el motor acelerado, su
velocidad será lo suficientemente rápida
para que el embrague engrane el piñón
y haga girar la cadena.
Tan pronto arranque, accione
inmediatamente por un breve momento
el gatillo de aceleración para
desconectarlo de la posición de
arranque y permitir que el motor se
desacelere a la marcha en vacío.
Con el motor funcionando a marcha en
vacío solamente, enganche la
herramienta motorizada al gancho de
resorte de su arnés (vea el capítulo
correspondiente en este manual).
ADVERTENCIA
Cuando tire del mango de arranque, no
enrolle la cuerda de arranque alrededor
de la mano. No deje que el mango
vuelva por solo a su posición original,
sino guíe lentamente la cuerda con la
mano para que se enrolle
correctamente. Si no ejecuta este
procedimiento puede lastimarse la
mano o los dedos y también dañar el
mecanismo de arranque.
Ajustes importantes
ADVERTENCIA
Para reducir el riesgo de lesiones
personales debido a la pérdida de
control o al contacto con la herramienta
de corte en movimiento, no use una
máquina cuyo régimen de marcha en
vacío está mal regulado. Cuando el
régimen de marcha en vacío está
correctamente regulado, la cadena de
aserrado no debe moverse. Para
instrucciones acerca de cómo ajustar el
régimen de marcha en vacío, vea la
sección correspondiente del manual de
instrucciones.
Si no puede regular correctamente la
marcha en vacío, pida a su
concesionario STIHL que revise la
herramienta motorizada y haga los
ajustes o reparaciones
correspondientes.
Es importante mantener la cadena
correctamente tensada. Revísela
periódicamente (durante los descansos
y cuando se apague el podador de
varilla). Si durante el corte la cadena
llega a aflojarse, apague el motor y
ajuste la tensión. Nunca trate de tensar
la cadena mientras el motor está
funcionando.
Durante el funcionamiento
Sujeción y control de la herramienta
motorizada
Al trabajar, siempre sujete la máquina
firmemente con ambas manos en los
mangos. Cierre firmemente los dedos y
pulgares sobre los mangos.
Coloque la mano izquierda sobre el eje
y la derecha sobre la empuñadura
trasera y el gatillo de aceleración. Los
zurdos también deben seguir estas
instrucciones. Mantenga las manos en
esta posición para guardar el control del
podador de varilla en todo momento
mientras trabaja.

ADVERTENCIA
Nunca intente manejar la herramienta
motorizada con una sola mano. La
pérdida de control de la herramienta
motorizada puede ocasionar lesiones
graves o mortales.
ADVERTENCIA
Para mantener el control del podador de
varilla, siempre tenga bien apoyados y
equilibrados los pies. No trabaje sobre
una escalera, en un árbol o cualquier
otro punto de apoyo que no sea seguro.
Nunca mantenga la máquina a una
altura más arriba de los hombros. No
trate de alcanzar más lejos de lo debido.
Si se va a trabajar a una altura de más
de 4,5 m (15 pies), utilice un canasto
elevador. En el podador de varilla con
eje ajustable, alargar el eje sólo lo
necesario para el trabajo deseado.
ADVERTENCIA
Se debe tener cuidado especial cuando
las condiciones del suelo son
resbaladizas (suelo húmedo, nieve) y en
terreno difícil y con mucha vegetación.
Para evitar tropezarse, esté atento a los
obstáculos ocultos, tales como tocones,
raíces, piedras, hoyos y zanjas. Para
obtener un punto de apoyo seguro, quite
las ramas caídas, los matorrales y el
material cortado. Sea sumamente
precavido cuando trabaje en declives o
terreno irregular.
ADVERTENCIA
Proceda con sumo cuidado cuando
trabaje en condiciones climáticas
húmedas o frías (lluvia, nieve, hielo).
Interrumpa el trabajo cuando hay
condiciones de mucho viento, tormenta
o lluvia intensa.
Condiciones de trabajo
Maneje y arranque su herramienta
motorizada solamente al aire libre en un
lugar bien ventilado. Manéjela
solamente en condiciones de buena
visibilidad y a la luz del día. Trabaje con
mucho cuidado.
ADVERTENCIA
Tan pronto arranca, esta
máquina genera vapores
de escape tóxicos que
contienen productos quí-
micos (tales como
hidrocarburos sin quemar
y monóxido del carbono,
incluyendo el benceno)
considerados como cau-
santes de enfermedades
respiratorias, cáncer,
defectos de nacimiento u
otra toxicidad reproduc-
tora. Algunos de estos
gases (por ej., monóxido
de carbono) pueden ser
incoloros e inodoros y
pueden causar asfixia o
muerte muy rápidamente.
Para reducir el riesgo de
sufrir lesiones graves o
mortales por respirar
gases tóxicos, nunca
haga funcionar la
máquina puertas adentro
o en lugares mal ventila-
dos. Si debido a la falta
de ventilación adecuada
los gases de escape se
concentran, elimine los
obstáculos de la zona de
trabajo para obtener ven-
tilación adecuada antes
de proceder y/o tome
descansos frecuentes
para permitir la disipación
de los gases antes de
que se puedan
concentrarse.

ADVERTENCIA
La inhalación de ciertos polvos,
especialmente los polvos orgánicos,
tales como el moho o polen, puede
provocar reacciones alérgicas o
asmáticas en las personas sensibles.
La inhalación repetida o de grandes
cantidades de polvo u otros
contaminantes del aire, especialmente
los de partículas pequeñas puede
causar enfermedades respiratorias o de
otro tipo. Esto incluye el polvo,
especialmente de las maderas duras,
pero también de algunas maderas
blandas, tales como el cedro rojo
occidental. Controle el polvo en su
fuente, siempre que sea posible. Utilice
buenas prácticas de trabajo, tal como
siempre cortar con una cadena bien
afilada (que produce virutas de madera
en vez de polvo fino) y trabajar de
manera que el viento o el proceso de
corte dirige el polvo producido por la
herramienta motorizado en sentido
opuesto del operador. Observe las
recomendaciones emitidas por
EPA/OSHA/NIOSH y las asociaciones
de trabajo y los sindicatos con respecto
al polvo ("materia particulada"). Cuando
sea imposible eliminar
significativamente la inhalación del
polvo, es decir mantener el nivel cerca
del valor ambiente, el operador y las
personas que se encuentren en la
cercanía siempre deberán usar un
respirador aprobado por NIOSH/MSHA
para el tipo de polvo presente en el
lugar.
ADVERTENCIA
La aspiración del polvo de asbesto es
peligrosa y puede causar lesiones
graves o mortales, enfermedades de las
vías respiratorias o cáncer. El uso y la
eliminación de los productos que
contienen asbesto están estrictamente
reglamentados por OSHA y el
Organismo para la Protección del Medio
Ambiente (EPA) de los EE.UU. Si por
cualquier motivo cree que está cortando
asbesto, póngase en contacto
inmediatamente con su empleador o un
representante de OSHA local.
ADVERTENCIA
Para reducir el riesgo de que otras
personas sufran lesiones graves o
mortales causadas por la caída de
objetos, o el contacto inesperado con la
cadena en movimiento de la
herramienta motorizada, siempre
mantenga a las demás personas a una
distancia no menor de 15 m (50 pies) de
la herramienta motorizada cuando se
encuentre en marcha.
ADVERTENCIA
Si bien es necesario mantener los
terceros lejos de la motosierra en
marcha, nunca trabaje solo.
Manténgase a una distancia que le
permita comunicarse con otras
personas en caso de necesitar ayuda.
Apague el motor inmediatamente si se
le aproxima alguna persona.
PELIGRO
La electricidad puede saltar de un punto
a otro al formar arcos en el aire. Los
niveles altos de voltaje aumentan la
distancia sobre la cual la electricidad
puede formar arcos. La electricidad
también puede conducirse por las
ramas de un árbol, especialmente si
éstas están húmedas. Guarde una
distancia no menor de 15 m (50 pies)
entre el podador de varilla (incluyendo
las ramas con las cuales tenga
contacto) y todas las líneas que
conduzcan corriente eléctrica. Antes de
trabajar a una distancia menor,
comuníquese con la empresa de
Su herramienta motori-
zada no está aislada
contra las sacudidas
eléctricas. Para reducir el
riesgo de electrocución,
nunca utilice esta herra-
mienta motorizada cerca

servicio eléctrico y comprobar que se
haya interrumpido el suministro
eléctrico.
Instrucciones de manejo
ADVERTENCIA
No maneje su herramienta motorizada
usando la posición de arranque del
acelerador, dado que usted no puede
controlar la velocidad del motor.
En caso de emergencia, apague el
motor inmediatamente pulsando el
interruptor de parada.
ADVERTENCIA
Para reducir el riesgo de lesionarse,
mantenga las manos y los pies alejados
de la cadena de aserrado. No toque
nunca con las manos o cualquier parte
del cuerpo la cadena que está en
movimiento. La cadena de aserrado
sigue en marcha por un rato después
que se suelta el gatillo de aceleración
(efecto de inercia).
Al aumentar la velocidad del motor con
la cadena bloqueada se aumenta la
carga y se provoca el patinaje continuo
del embrague. Esto puede causar
sobrecalentamiento y daño de los
componentes importantes (por ejemplo,
el embrague y las piezas de plástico
polimérico de la caja) que, a su vez,
aumenta el riesgo de lesiones causadas
por el movimiento de la cadena cuando
el motor está en marcha a vacío.
ADVERTENCIA
Si la cadena se atasca, siempre apague
el motor y asegúrese que la cadena está
detenida antes de limpiarla.
Asegúrese que la cadena de aserrado
no toque ninguna materia extraña como
por ejemplo rocas, cercas, clavos y
cosas por el estilo. Tales objetos
pueden ser lanzados y lesionar al
operador o a terceros y dañar la cadena
de aserrado.
ADVERTENCIA
Antes de recortar las ramas, despeje de
zona de trabajo las ramas y matorrales
que puedan causar interferencia.
Después, establezca un lugar de
escape de la zona de caída de las
ramas y retire todos los obstáculos.
Mantenga despejada la zona de trabajo
quite las ramas caídas. Coloque todas
las herramientas y el equipo a una
distancia prudente de las ramas
recortadas, pero no en la zona de
escape.
ADVERTENCIA
Siempre observe la condición general
del árbol. Busque evidencia de deterioro
y pudrición en el tronco y en las ramas.
Si está podrido en su interior, podría
romperse repentinamente y caer hacia
el operador cuando está siendo
recortado. Siempre busque las ramas
quebradas o muertas que puedan
soltarse con la vibración y caerle
encima. Si la rama es gruesa o pesada,
haga un corte de distensión no muy
profundo en la parte inferior de la rama
antes de cortarla por su parte superior
para evitar que la rama se parta.
Consulte el capítulo "Uso de la
máquina".
ADVERTENCIA
Para reducir el riesgo de lesiones
graves o mortales causadas por la caída
de objetos, no haga cortes directamente
sobre su cuerpo. Sostenga el podador
de varilla a un ángulo no mayor que 60°
respecto a la horizontal (vea la
ilustración). Los objetos pueden caer en
direcciones no anticipadas. No se pare
directamente debajo de la rama que es
está recortando!
Esté atento a la caída de las ramas. Tan
pronto la rama recortada empieza a
caer, apártese y guarde una distancia
adecuada de la rama.
ADVERTENCIA
Siempre saque la máquina del corte con
la cadena todavía en marcha para
reducir la posibilidad de atrapar el
accesorio de corte. No ejerza presión
sobre el podador de varilla cuando
246BA030 KN
HT 102, HT 103, HT 132, HT 133
español / EE.UU
55
llegue al final del corte. La presión
puede hacer que la espada y la cadena
en movimiento salten fuera de la ranura
de corte o entalla, perdiéndose el control
y golpeando otro objeto.
Si la espada queda aprisionada en la
rama de modo que la cadena ya no
pueda moverse, apague el podador de
varilla y mueva la rama con cuidado
para aflojar la estricción y liberar la
espada.
ADVERTENCIA
Si una cadena de aserrado en
movimiento chocara contra una roca u
otro objeto macizo, se podrían despedir
chispas capaces de encender
materiales inflamables en determinadas
circunstancias. Entre los materiales
inflamables se incluyen la vegetación y
arbustos secos, en particular cuando el
estado del tiempo es caliente y seco. Si
existe un riesgo de incendio leve o
grave, no use herramientas motorizadas
alrededor de materiales inflamables, ni
para cortar vegetación o arbustos
secos. Comuníquese con las
autoridades locales de control de
incendios o con el servicio forestal de
los EE. UU. si tiene alguna duda en
cuanto a las condiciones de la
vegetación y el estado del tiempo para
el uso de una podador de varilla.
ADVERTENCIA
Nunca modifique el silenciador. La
modificación del silenciador podría
causar el aumento del calor irradiado,
de las chispas y del nivel de ruido, lo que
aumentará el riesgo de incendios,
lesiones por quemadura o la pérdida
auditiva. Además, se podría dañar
permanentemente el motor. STIHL
recomienda que haga reparar el
silenciador únicamente por el
concesionario de servicio STIHL.
ADVERTENCIA
El silenciador y otros componentes del
motor (por ej., aletas del cilindro, bujía)
se calientan durante el funcionamiento y
permanecen calientes por un buen rato
después de apagar el motor. Para
reducir el riesgo de quemaduras, no
toque el silenciador ni los otros
componentes mientras están calientes.
Mantenga limpia la zona alrededor del
silenciador. Quite el lubricante excesivo
y toda la basura tal como las agujas de
pinos, ramas u hojas. Deje que el motor
se enfríe apoyado sobre una superficie
de hormigón, metal, suelo raso o
madera maciza (por ej., el tronco de un
árbol caído) lejos de cualquier sustancia
combustible.
ADVERTENCIA
Una caja de cilindro dañada o mal
instalada, o una envuelta del silenciador
dañada o deformada, puede perjudicar
el proceso de enfriamiento del
silenciador. Para reducir el riesgo de
incendio o lesiones por quemadura, no
continúe trabajando con una caja de
cilindro dañada o mal instalada, o una
envuelta del silenciador dañada o
deformada.
El silenciador tiene un chispero
diseñado para reducir el riesgo de
incendio debido a la emisión de
partículas calientes. Nunca haga
funcionar la unidad sin tener instalado el
chispero. Si la mezcla de gasolina y
aceite está correcta (no es demasiado
rica), en condiciones normales el
chispero quedará limpio como resultado
del calor del silenciador y no necesitará
servicio ni mantenimiento. Si el
rendimiento de su máquina comienza a
disminuir y sospecha que las rejillas
están obstruidas, haga reparar el
silenciador por un concesionario de
servicio STIHL. Para ciertas
aplicaciones, las leyes o los
reglamentos estatales o federales
pueden requerir el uso de un chispero
en buenas condiciones. Consulte la
sección "Mantenimiento, Reparación y
Almacenamiento" de estas Medidas de
seguridad. Recuerde que el riesgo de
incendios de matorrales o forestales es
mayor durante las estaciones calurosas
y secas.
Fuerzas reactivas
ADVERTENCIA
Las fuerzas reactivas pueden ocurrir en
cualquier momento mientras la cadena
está girando. La fuerza utilizada para
cortar madera puede cambiar de sentido
y actuar contra el operador. Si una
cadena en movimiento se detiene
repentinamente al tocar un objeto sólido
como por ejemplo una rama, o bien
queda aprisionada, pueden presentarse
de inmediato las fuerzas reactivas. Esas
fuerzas reactivas pueden causar la
pérdida del control, lo que a su vez
puede causar lesiones personales. Una
buena comprensión de las causas de
estas fuerzas reactivas puede ayudarle
a evitar el elemento de sorpresa y la
pérdida del control.
Debido a su diseño, las fuerzas
reactivas producidas al trabajar con el
podador de varilla, por lo general, no
HT 102, HT 103, HT 132, HT 133
español / EE.UU
56
son tan severas como las producidas
por una motosierra. No obstante,
siempre agarre firmemente la
herramienta motorizada y tenga buen
apoyo para los pies para mantener el
control cuando se producen tales
fuerzas.
Las fuerzas reactivas más comunes
son:
contragolpe,
rechazo,
tirón.
Contragolpe
El contragolpe puede ocurrir cuando la
cadena en movimiento cerca del
cuadrante superior de la punta de la
espada toca un objeto sólido o queda
aprisionada.
La reacción de la fuerza de corte de la
cadena causa una fuerza de rotación en
el podador de varilla en sentido contrario
al movimiento de la cadena. Esto puede
causar el movimiento hacia arriba de la
espada.
Para evitar el contragolpe
La mejor protección contra un
contragolpe es evitar las situaciones de
contragolpe:
1. Sea consciente de la ubicación de
la punta de la espada en todo
momento.
2. Nunca deje que la punta de la
espada haga contacto con ningún
objeto. No corte ramas con la punta
de la espada. Preste especial
atención al trabajar cerca de vallas
de alambre y cuando corte ramas
pequeñas y duras que pueden
fácilmente quedar enredados en la
cadena.
3. Corte solamente una rama a la vez.
A = Tirón
El tirón ocurre cuando la cadena en la
parte inferior de la espada se detiene
repentinamente cuando queda
aprisionada, retenida o choca con algún
objeto extraño en la madera. La
reacción de la cadena tira del podador
de varilla hacia adelante.
A menudo, el tirón ocurre cuando la
cadena no está a plena velocidad antes
de quedar en contacto con la madera.
Para evitar los tirones
1. Esté alerta a las fuerzas o
situaciones que pueden permitir
que el material aprisione la cadena
en la parte inferior de la espada.
2. Siempre empiece el corte con la
cadena girando a velocidad
máxima.
B = Rechazo
El rechazo ocurre cuando la cadena en
la parte superior de la espada se detiene
repentinamente cuando queda
aprisionada, retenida o choca con algún
objeto extraño en la madera. La
reacción de la cadena puede impulsar
repentinamente el podador de varilla
hacia atrás contra el operador. El
rechazo frecuentemente ocurre cuando
se utiliza la parte superior de la espada
para hacer los cortes.
Para evitar el rechazo
1. Esté alerta a las fuerzas o
situaciones que pueden permitir
que el material aprisione la cadena
en la parte superior de la espada.
2. No corte más de una rama a la vez.
3. No tuerza la espada al retirarla de
un corte por debajo, porque la
cadena puede quedar aprisionada.

MANTENIMIENTO, REPARACIÓN Y
ALMACENAMIENTO
Los trabajos de mantenimiento,
reemplazo o reparación de los
dispositivos y sistemas de control de
emisiones de escape pueden ser
realizados por cualquier taller o técnico
de motores no diseñados para
vehículos. Sin embargo, si usted está
reclamando servicio de garantía para
algún componente que no ha sido
reparado o mantenido debidamente,
STIHL puede denegar la garantía.
ADVERTENCIA
STIHL recomienda el uso de piezas de
repuesto originales STIHL para el
mantenimiento y reparación. El uso de
piezas de otros fabricantes puede ser
extremadamente peligroso y causar
lesiones graves o mortales.
Siga precisamente las instrucciones de
mantenimiento y reparación dadas en
las secciones correspondientes del
manual de instrucciones. Consulte la
tabla de mantenimiento en este manual.
ADVERTENCIA
Siempre apague el motor y verifique que
la cadena está parada antes de llevar a
cabo cualquier trabajo de
mantenimiento, reparación o limpieza
de la herramienta motorizada. No
intente hacer ningún trabajo de
mantenimiento o reparación que no esté
descrito en este manual de
instrucciones. STIHL recomienda que
este tipo de trabajo debe realizarse
únicamente por un concesionario de
STIHL autorizado para servicio.
Use guantes para manipular o efectuar
trabajos de mantenimiento de la
herramienta de corte.
ADVERTENCIA
Para reducir el riesgo de incendio y de
quemaduras o daños a la propiedad,
utilice solamente las bujías autorizadas
por STIHL. Siempre inserte el casquillo
de la bujía bien apretado en el borne de
la bujía del tamaño adecuado. (Nota: Si
el borne tiene una tuerca adaptadora
SAE desmontable, la misma tiene que
ser firmemente instalada.) Una
conexión suelta entre el borne de la
bujía y el conector del cable de
encendido en el casquillo puede crear
un arco voltaico y encender los vapores
del combustible, provocando un
incendio. Mantenga la bujía limpia, y
asegúrese que el conductor de
encendido esté en buen estado.
ADVERTENCIA
No pruebe nunca el sistema de
encendido con el casquillo del cable de
encendido desconectado de la bujía, o
sin tener instalada la bujía, ya que las
chispas al descubierto pueden causar
un incendio.
ADVERTENCIA
Nunca maneje su herramienta
motorizada si el silenciador está
dañado, se ha perdido o si fue
modificado. Un silenciador mal cuidado
aumenta el riesgo de incendio y puede
causar pérdida de audición. El
silenciador está equipado con un
chispero para reducir el riesgo de
incendio; no maneje nunca su
herramienta motorizada si le falta el
chispero o está dañado. Recuerde que
el riesgo de incendios de matorrales o
forestales es mayor durante las
estaciones calurosas y secas.
En California, constituiría una violación
de los acápites § 4442 o § 4443 del
Código de Recursos Públicos el uso de
herramientas con motor de gasolina en
tierras cubiertas por bosques, arbustos
o pastos, a menos que el sistema de
escape del motor cuente con un
parachispas que satisfaga los requisitos
legales y reciba un mantenimiento
adecuado para estar en buenas
condiciones de funcionamiento. El
propietario/operador de este producto
es responsable del mantenimiento
adecuado del chispero. Otras
entidades/agencias estatales o
gubernamentales, tales como el
Servicio Forestal de los EE.UU., pueden
tener requisitos similares. Comuníquese
con el cuerpo de bomberos de su
localidad o con el servicio forestal para
informarse en cuanto a las leyes y
reglamentos relacionados con los
requisitos de protección contra
incendios.
ADVERTENCIA
Mantenga limpias la cadena, la espada
y el piñón; sustituya los piñones o las
cadenas desgastados. Mantenga
afilada la cadena. Podrá notar que la
cadena está desafilada cuando la
madera fácil de cortar exige gran
esfuerzo y cuando aparecen marcas de
quemaduras en la madera. Mantenga la
cadena correctamente tensada.
Apriete todas las tuercas, pernos y
tornillos, excepto los tornillos de ajuste
del carburador, después de cada uso.

Corte transversal
Para que la espada no quede
aprisionada en el corte, coloque el
accesorio de corte con la carcasa contra
la rama y luego lleve a cabo el corte
transversal de arriba hacia abajo.
Corte de distensión
Para evitar arrancar la corteza al
recortar ramas gruesas, siempre haga
primero un corte de distensión (1) en el
lado inferior de la rama.
N Para hacer esto, coloque el
accesorio de corte y tire del mismo
a lo ancho de la parte inferior de la
rama en forma de arco, hasta llegar
a la punta de la espada.
N Haga el corte transversal (2) –
coloque la espada con la carcasa
contra la rama.
Corte a ras de ramas gruesas
Si el diámetro de la rama supera los
10 cm (4 pulg), primero
N realice un corte en el lado
inferior (3) y luego haga un corte
transversal a unos 20 cm/8 pulg (A)
del corte final. Después haga el
corte a ras (4), empezando con un
corte de distensión y terminando
con el corte transversal.
Corte sobre obstáculos
El largo alcance de la máquina posibilita
el recorte de ramas que se proyectan
sobre obstáculos, tales como los ríos y
lagos. El ángulo de la herramienta en
este caso depende de la posición de la
rama.
Corte desde un canasto elevado
El largo alcance de la máquina permite
cortar junto al tronco sin el riesgo de que
el canasto dañe otras ramas. El ángulo
de la herramienta en este caso depende
de la posición de la rama.

Para la lubricación automática y
confiable de la cadena y espada utilice
exclusivamente un lubricante de
calidad, compatible con el medio
ambiente, diseñado para uso con
cadenas y espadas. Se recomienda el
aceite STIHL BioPlus, el cual es
rápidamente biodegradable.
INDICACIÓN
El aceite de cadena biodegradable debe
ser resistente al envejecimiento (por
ejemplo, STIHL BioPlus), pues de lo
contrario se convertiría rápidamente en
resina. Esto produce como resultado
depósitos sólidos difíciles de quitar,
especialmente en las zonas del mando
de la cadena y la cadena misma. Hasta
puede causar el agarrotamiento de la
bomba de aceite.
La vida útil de la cadena y de la espada
depende de la calidad del lubricante.
Por lo tanto, es esencial usar un
lubricante de cadena de formulación
especial.
ADVERTENCIA
No use aceite de desecho. El contacto
repetido con aceite de desecho puede
causar cáncer en la piel. Además, el
aceite de desecho es dañino para el
ambiente.
INDICACIÓN
El aceite de desecho no tiene las
propiedades lubricantes necesarias y no
es adecuado para la lubricación de
cadenas.

comuníquese con el concesionario para
recibir ayuda, de ser necesario. STIHL
recomienda que un concesionario
STIHL autorizado efectúe los trabajos
de mantenimiento y reparación.

N Dé vuelta a la espada – cada vez
que afile la cadena y cada vez que
sustituya la cadena – con ello
ayudará a evitar que se produzca
desgaste por un solo lado,
especialmente en la punta y la cara
inferior de la espada.
N Limpie regularmente el orificio de
entrada de aceite (1), el conducto
de aceite (2) y la ranura de la
espada (3).
N Mida la profundidad de la ranura,
con el calibrador de rectificación
(accesorio especial), en la zona
utilizada para la mayoría de los
cortes.
Si la profundidad de la ranura es menor
que la especificada:
N Sustituya la espada.
De lo contrario las pestañas de los
eslabones impulsores rasparán la parte
inferior de la ranura – los cortadores y
las amarras no viajarán sobre los rieles
de la espada.
La vida útil promedio de los filtros es
más de 1 año. No quite la cubierta del
filtro a menos que se produzca una
pérdida notable de potencia del motor.
Si se nota una pérdida considerable de
la potencia del motor
N Gire la perilla del estrangulador a
g.
N Afloje los tornillos (1).
N Quite la cubierta del filtro (2).
N Limpie toda la suciedad de
alrededor del filtro.
N Quite el elemento del filtro (3).
