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 mak
e 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

An air filter that has been in use f
or 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 ma
y result in oper
ating problems and starting
difficulties.
If the machine is low on power, difficult to start or runs poorly
at idle speed: alw

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
