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

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 PARTNER 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 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.
