MAINTENANCE
Fuel filter
The fuel filter sits inside the fuel tank.
The fuel tank must be protected from contamination when
filling. This reduces the risk of operating disturbances caused
by blockage of the fuel filter.
The filter cannot be cleaned but must be replaced with a new
filter when it blocked. The filter should be changed at least
once per year.

A
Air filter
The air filter should be
cleaned regularly removing
dust and dirt to avoid:
Carburettor malfunction
Starting problems
Reduced engine power
Unnecessary wear to
engine parts
Abnormal fuel consumption
The air filter system consists
of a main filter and a back-up
filter:
1)The main-filter is an oiled
foam filter that is easily
accessible under the filter
cover A. When used in
dusty conditions, this filter
should be checked/
replaced after every second
tank of fuel. The filter must
be cleaned and oiled
regularly to obtain a
satisfactory filtering effect.
There is a special
HUSQVARNA oil produced
for this purpose.
Remove the filter. Wash the
filter carefully in tepid,
soapy water. After cleaning
rinse the filter thoroughly in
clean water. Squeeze out
the filter and let the filter
dry. NOTE! Compressed air
at a high pressure can
damage the foam.
Oil the filter carefully. It is extremely important that the entire
filter is saturated in oil.
2)The back-up filter is a paper filter and is accessible from
under cover B. This filter should be changed/cleaned when
the engines output drops or after 1-2 weeks. The filter is
cleaned by shaking or carefully using compressed air. Note
the filter must not be washed!
A filter used for a long period of time can never be completely
cleaned. Therefore all air filters must be replaced periodically
with a new filter. A damaged air filter must always be
replaced.
IMPORTANT INFORMATION!
Insufficient care of the air filter will cause deposits on
the spark plug resulting in abnormal wear to engine
parts.
