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.

Air filter

The air filter should be cleaned regularly removing dust and dirt

to avoid:

 

Carburettor malfunction

 

Starting problems

2

Reduced engine power

Unnecessary wear to

1

 

 

engine parts

 

A

The air filter system consists of a pre-filter (1) and a main filter (2):

1)The pre-filter is an oiled

B

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 main filter is a paper filter and is accessible from under cover B. This filter should be changed/cleaned when the engine’s 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.
