MAINTENANCE
34 – English
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
that the electrode gap is 0.020 inch (0.5 mm). The spark plug
should be replaced after about a month in operation or
earlier if necessary.
Note! Always use the recommended spark plug type! Use of
the wrong spark plug can damage the piston/cylinder. Check
that the spark plug is fitted with a suppressor.
