MAINTENANCE

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.

AutoTune

The engine is equipped with AutoTune, so manual adjustment of the carburettor’s H and L needles and the T- screw no longer applies. Both needles and the T-screw have been removed. AutoTune is a function that adjusts the carburettor electronically, always resulting in optimal adjustment.

WARNING! If the saw chain rotates while

! idling, contact your servicing dealer. Do not use the chain saw until it has been properly adjusted or repaired.

Function

•The carburettor controls the speed of the engine via the throttle. Air/fuel is mixed in the carburettor. This air/ fuel mixture is adjustable.

•The automatic adjustment of the carburettor means that the engine is adapted to local conditions, e.g. the climate, altitude, petrol and the type of 2-stroke oil. This function is controlled by AutoTune.

Engine adjustment

The following steps should be taken when the chain saw is started for the first time or when outside circumstances change (fuel, altitude, air filter etc.):Start the engine.

Accelerate the engine and saw a number of cuts in a thick log (3-5 min.). The chain saw must be run (8,000 - 12,000 rpm) the entire time so that the carburettor can adjust itself.

When working for long periods in young forest with small dimensions and/or much limbing, the cutting process must be performed more frequently often on thicker logs. Cutting must be done with with full throttle under load. This is so that the carburettor’s automatic control function can be activated.

Conditions

NOTE! The ignition system includes an in-built speed limiter. When the speed governor is activated, you will get the same sound experience as when the chain saw 4- cycles.

Checking, maintaining and servicing chain saw safety equipment

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.

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.

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.
