Maintenance

The main filter has a paper insert that is changed as follows.

1Open the engine cover.

2Unscrew the filter cover and remove the paper filter.

Cleaning the air filter

If the engine seems to lack power or does not run smoothly this may be because the air filter is clogged. When driving with a dirty air filter the engine can suffer from lack of air, so that it does not meet environmental requirements and the engine does not provide full power.

Emptying the particle collector

Squeeze so that the rubber tabs open and the particles can escape.

Cleaning the filter cover

Loosen the two fasteners holding the filter cover and remove it.

Clean the inside of the lid. It can be washed with soapy water and blown with compressed air when the lid is removed.

Replace the air filter cover, ensure that the particle collector is facing downwards.

Replacing the air filter

!

WARNING! The exhaust system is hot. Let it

cool before starting to replace the air filter.

 

If the engine seems to lack power or does not run smoothly this may be because the air filter is clogged. It is therefore important to replace the air filter at regular intervals (see Maintenance/Maintenance Schedule for the correct service interval).

Replace the air filter as follows:

•Open the engine cover.

•Loosen the two fasteners holding the filter cover and remove it.

IMPORTANT INFORMATION

Never run the engine without the air filter fitted.

Poorly filtered inlet air is a main factor contributing to engine wear. Replace the air filter according to the service schedule or more often in dusty conditions

The filters must not be oiled. They must be fitted dry.

•Remove the filter cartridge from the filter housing.

•Wipe clean the interior of the air filter housing. If necessary, the cleaning cloth should be moistened with white spirit or fuel. Water or compressed air should not be used.

•Clean the filter by knocking it with care against a hard surface. Do not use compressed air to clean the filter. Replace the air filter if it is still dirty.

3Fit a new air filter cartridge with the hole inward and press it into place.

4Replace the air filter cover, ensure that the particle collector is facing downwards.

Cleaning the engine and muffler

Keep the engine and muffler free from grass cuttings and dirt. Clipping debris soaked in fuel or oil on the engine means increased risk of fire and impaired cooling.

Allow the engine to cool before cleaning. If the dirt is mixed with oil, remove it using a degreasing agent otherwise just water and a brush.

Grass cuttings around the muffler dry quickly and constitute a fire risk. Brush or wash them off when the muffler is cold.
