MAINTENANCE
Tensioning the recoil spring
Hook the starter cord in the notch in the pulley and turn
the starter pulley about 2 turns clockwise.
Note! Check that the pulley can be turned an additional 1/
2 turn when the starter cord is pulled all the way out.
Changing a broken recoil spring
Lift up the starter pulley. See instructions under the
heading Changing a broken or worn starter cord.
Remember that the recoil spring is coiled under tension in
the starter housing.
Remove the cassette with the recoil spring from the
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.
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.
Spark plug
The spark plug condition is influenced by:
Incorrect carburetor adjustment.
An incorrect fuel mixture (too much or incorrect type of
oil).
A dirty air filter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.
If the machine is low on power, difficult to start or runs poorly
at idle speed: always check the spark plug first before taking
any further action. If the spark plug is dirty, clean it and check
