MAINTENANCE

General

The user must only carry out the maintenance and service work described in this manual. More extensive work must be carried out by an authorized service workshop.

Carburetor adjustment

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

Function

The carburetor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburetor. 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 carburetor 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 idling 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 counter- clockwise until the chain stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position. It should also be good margin to the rpm when the chain starts to rotate.

WARNING! Contact your servicing

! dealer, if the idle speed setting cannot be adjusted so that the chain stops at idle. Do not use the chain saw until it has been properly adjusted or repaired.

Correctly adjusted carburetor

When the carburetor is correctly adjusted the machine accelerates without hesitation and the machine 4-cycles a little at max. speed. 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

Note! All servicing and repair work on the machine requires special training. This is especially true of the machines safety equipment. If your machine fails any of the checks described below we recommend you to contact our servicing dealer.

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 0.024 inch (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

With the engine turned off, hold the chain saw over a stump or other firm object. Let go of the front handle so that the bar drops towards the stump as the chain saw rotates around the rear handle. (92)

When the bar hits the stump the brake should be applied. (93)

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)

Grasp the chain saw firmly, wrapping your fingers and thumbs around the handles. (56)

Apply full throttle and activate the chain brake by tilting your left wrist forward onto the front hand guard. Do not let go of the front handle. The chain should stop

immediately. (52)
