MAINTENANCE
MAINTENANCE, REPLACEMENT OR REPAIR OF THE
EMISSION CONTROL DEVICES AND SYSTEMS MAY
BE PERFORMED BY ANY NON-ROAD ENGINE REPAIR
ESTABLISHMENT OR INDIVIDUAL.
Carburetor adjustment (Fig. 13)
The carburetor is a precision part that mixes air and fuel, and
it is designed to ensure high performance from the engine.
Before the tool is shipped from the factory, its carburetor is
adjusted during a test run. Only make adjustments if it is
necessary because of environmental conditions (the climate
or atmospheric pressure), the type of fuel, the type of two-
cycle oil, etc.
WARNING
Because the carburetor is manufactured with a high
degree of precision, do not disassemble it.
For this product, the only setting of the carburetor that
can be adjusted is the idle speed (T).
T = Idle speed adjustment screw.
Idle speed adjustment (T)
Check that the air lter is clean. If adjustment is required,
turn IDLE speed Adjustment Screw (T) close (clockwise)
to increase engine speed, open (counterclockwise) to
decrease engine speed. Standard Idle rpm is 2800-
3200 rpm.
CAUTION
The above adjusting procedure must be followed when
adjustment is MADE or DAMAGE to engine will occur
because of the incorrect condition.
NOTE
Some models sold areas with strict exhaust emission
regulation do not have high and low speed carburetor
adjustments. Such adjustments may allow the engine to
be operated outside of their emission compliance limits.
For these models, the only carburetor adjustment is idle
speed.
RECOMMENDATION
CARBURETOR ADJUSTMENT NEEDS THE SKILL
OF EXPERIENCED OR WELL TRAINED PEOPLE, OR
IS RECOMMENDED TO TAKE THE UNIT TO HiKOKI
Authorized Service Centers.
Air lter (Fig. 14)
The air lter (11) must be cleaned from dust and dirt in order
to avoid:
Carburetor malfunctions.
Starting problems.
Engine power reduction.
Unnecessary wear on the engine parts.
Abnormal fuel consumption.
Clean the air lter daily or more often if working in
exceptionally dusty areas.
Cleaning the air lter (Fig. 14)
Open the air lter cover (12) and remove the air lter (11).
Clean it.
Check that the lter is dry before reassembly.
An air lter that has been used for some time cannot be
cleaned completely. Therefore, it must regularly be replaced
with a new one. A damaged lter must always be replaced.
Fuel lter (Fig. 15)
Remove the fuel lter (13) from the fuel tank, and replace it
if it is dirty.
NOTE
A blocked fuel lter (13) can prevent the supply of fuel
and cause a rotation malfunction of the engine.
Spark plug (Fig. 16)
When removing the spark plug, twist and remove the plug
cap covering the spark plug as shown in the illustration.
(Fig. 17)
The spark plug condition is in uenced by:
An incorrect carburetor setting.
Wrong fuel mixture (too much oil in the gasoline)
A dirty air lter.
Hard running conditions (such as cold weather).
These factors cause deposits on the spark plug electrodes,
which may result in malfunction and starting di culties. If
the engine is low on power, di cult to start or runs poorly at
idling speed, always check the spark plug rst.
If the spark plug is dirty, clean it and check the electrode
gap. Re-adjust if necessary. The correct gap is 0.6 mm.
The spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly
eroded.
NOTE
In some areas, local law requires using a resistor spark
plug to suppress ignition signals. If this machine was
originally equipped with resistor spark plug, use same
type of spark plug for replacement.
For long-term storage
Drain all fuel from the fuel tank. Start and let engine run until
it stops. Repair any damage which has resulted from use.
Clean the unit with a clean rag, or the use of high pressure
air hose. Put a few drops of two-cycle engine oil into the
cylinder through the spark plug hole, and spin the engine
over several times to distribute oil.
Cover the unit and store it in a dry area.
