MAINTENANCE
General
Checking, maintaining and
servicing chain saw safety
equipment
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 authorised
service workshop.
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.
Carburettor adjustment
Your Husqvarna product has been designed and
manufactured to specifications that reduce harmful
emissions.
AutoTune
Chain brake and front hand guard
If the engine is equipped with AutoTune, 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.
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.
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.
Conditions
Regularly check that the brake band is at least 0.6 mm
thick at its thinnest point.
CAUTION! The ignition system includes an in-built speed
limiter, which prevents the speed of the engine exceeding
Checking the front hand guard
13,600
rpm. When the speed governor is activated, you
will get the same sound experience as when the chain
saw 4-cycles.
Correctly adjusted carburettor
Make sure the front hand guard is not damaged and that
there are no visible defects such as cracks.
A correctly adjusted carburettor means the machine
accelerates without hesitation and it four-strokes a little at
full throttle. In addition, the chain should not rotate when
idling.
Move the front hand guard forwards and back to make
sure it moves freely and that it is securely anchored to the
clutch cover.
