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.

Your Husqvarna product has been designed and 
manufactured to specifications that reduce harmful 
emissions. 

•

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.

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.

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.

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.

Brush off any wood dust, resin and dirt from the chain 
brake and clutch drum. Dirt and wear can impair operation 
of the brake. (84)

Regularly check that the brake band is at least 0,6 mm 
thick at its thinnest point.

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.

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. (85)

When the bar hits the stump the brake should be 
activated. (85)

Check that the right hand guard is not damaged and that 
there are no visible defects, such as cracks. (87)

Push the trigger up and forwards to check that it moves 
freely and is securely hinged to the clutch cover. (86)

Never carry or hang the saw by the trigger! This could 
damage the mechanism and disable the chain brake. 
(88)

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. 
(89)

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.
