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

A
The air filter system consists of a backup filter (1) and a main filter (2):
1) The main filter is an oiled | B |
foam rubber filter that is |
|
easily accessible under the |
|
filter cover (A). In dusty |
|
conditions this filter should |
|
be inspected/replaced each |
|
week. In order to obtain a |
|
good filtering effect, the filter |
|
must be cleaned and oiled |
|
regularly. Special |
|
HUSQVARNA oil has been |
|
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 backup filter is a paper filter accessible from under cover B. This filter should be replaced/cleaned when the engine’s power drops or each month. The filter is cleaned by shaking or by careful blowing with compressed air. Note that 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.
