tension in the starter housing.

starter.
Lubricate the recoil spring with light oil. Fit the
cassette with recoil spring in the starter. Fit the starter
pulley and tension the recoil spring.
Drive disc spring (B)
Undo the bolt in the centre of the pulley and remove
the drive disc and the drive disc spring.
Replace the drive disc spring and fit the drive disc
above the spring.
Fitting the starter
To fit the starter, first pull out the starter cord and place
the starter in position against the crankcase.Then
slowly release the starter cord so that the pulley
engages with the pawls.
Fit and tighten the screws that hold the starter.
Air filter
The air filter must be regularly cleaned to remove dust and
dirt in order to avoid:
Carburettor malfunctions
Starting problems
Loss of engine power
Unnecessary wear to engine parts
Excessive fuel consumption.
Remove the air filter after taking off the air filter cover.
When refitting make sure that the air filter seals tightly
against the filter holder. Clean the filter by brushing or
shaking it.
The filter can be cleaned more thoroughly by washing it in
water and detergent.
An air filter that has been in use for a long time cannot be
cleaned completely. The filter must therefore be replaced
with a new one at regular intervals. A damaged air filter
must always be replaced.
A HUSQVARNA chain saw can be equipped with different
types of air filters according to working conditions,
weather, season, etc. Contact your dealer for advice.
