MAINTENANCE
Air filter
Spark plug
The air filter must be regularly cleaned to remove dust
and dirt in order to avoid:
The spark plug condition is influenced by:
•
•
Incorrect carburettor adjustment.
•
•
•
•
•
•
Carburettor malfunctions
Starting problems
An incorrect fuel mixture (too much or incorrect type
of oil).
Loss of engine power
•
A dirty air filter.
Unnecessary wear to engine parts.
Excessive fuel consumption.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
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.
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 0.5 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.
The filter can be cleaned more thoroughly by washing it in
water and detergent.
Lubricating the bar tip sprocket
Lubricate the bar tip sprocket each time you refuel. Use
the special grease gun and a good quality bearing grease.
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 filter according to working conditions, weather,
season, etc. Contact your dealer for advice.
