MAINTENANCE

1153159-26 Rev.1 2009-12-29
General
The user must only carry out the maintenance and
service work described in this Operator’s Manual. More
extensive work must be carried out by an authorized
service workshop.
Carburettor adjustment
Your Husqvarna product has been designed and
manufactured to specifications that reduce harmful
emissions.
Function
The carburettor governs the engine’s speed via the
throttle control. Air and fuel are mixed in the
carburettor. The air/fuel mixture is adjustable. Correct
adjustment is essential to get the best performance
from the machine.
The T-screw regulates the throttle setting at idle
speed. If the T-screw is turned clockwise this gives a
higher idle speed; turning it anti-clockwise gives a
lower idle speed.
Basic settings and running in
The basic carburettor settings are adjusted during testing
at the factory. Fine adjustment should be carried out by a
skilled technician.
Rec. idle speed: See the Technical data section.
Fine adjustment of the idle speed T
Adjust the idle speed with the T-screw. If it is necessary to
re-adjust, turn the T-screw clockwise while the engine is
running, until the chain starts to rotate. Then turn anti-
clockwise until the chain stops. When the idle speed is
correctly adjusted the engine should run smoothly in
every position and the engine speed should be safely
below the speed at which the chain starts to rotate.
Correctly adjusted carburettor
When the carburettor is correctly adjusted the machine
accelerates without hesitation and 4-cycles a little at full
throttle. It is also important that the chain does not rotate
at idle. If the L-jet is set too lean it may cause starting
difficulties and poor acceleration. If the H-jet is set too
lean the machine will have less power, poor acceleration
and could suffer damage to the engine.
Checking, maintaining and
servicing chain saw safety
equipment
Chain brake and front hand guard
Checking brake band wear
Brush off any wood dust, resin and dirt from the chain
brake and clutch drum. Dirt and wear can impair
operation of the brake.
(91)
Regularly check that the brake band is at least 0.6 mm
thick at its thinnest point.
Checking the front hand guard
Make sure the front hand guard is not damaged and that
there are no visible defects such as cracks.
Move the front hand guard forwards and back to make
sure it moves freely and that it is securely anchored to the
clutch cover.
Checking the inertia brake release
Place the chain saw, with the engine switched off, on a
stump or other stable surface. Release the front handle
and let the saw fall by its own weight, rotating around the
rear handle towards the stump.
(92)
When the bar hits the stump the brake should be
applied.
(93)
Checking the right-hand brake trigger
Check that the right hand guard is not damaged and that
there are no visible defects, such as cracks.
(27)
Push the trigger up and forwards to check that it moves
freely and is securely hinged to the clutch cover.
(28)
Never carry or hang the saw by the trigger! This could
damage the mechanism and disable the chain brake.
(29)
Checking the brake trigger
Place the chain saw on firm ground and start it. Make sure
the chain does not touch the ground or any other object.
See the instructions under the heading Start and stop.
(94)
!
WARNING! Contact your servicing
dealer, if the idle speed setting cannot be
adjusted so that the chain stops. Do not
use the chain saw until it has been
properly adjusted or repaired.
Note! All service and repair work on the machine
demands special training. This is especially true of the
machine’s safety equipment. If your machine fails any of
the checks described below we recommend that you
take it to your service workshop.
