Replacing the air filter

!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:

1Open the engine cover.

2Loosen the two fasteners holding the filter cover and remove it.

IMPORTANT INFORMATION

Never run the engine without the air filter fitted.

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

3 Remove the filter cartridge from the filter housing.

4Clean the filter by knocking the filter carefully against a hard surface and blowing with compressed air from inside. Never brush the dirt away. Replace the air filter if it is very dirty.

PF 21 and PF 21 AWD have an additional filter located behind the filter cartridge. Clean the filter by knocking it with care against a hard surface. Do not use compressed air for this filter.

5Replace the filter cartridge. Make sure the filter cartridge is correctly fitted over the air intake in the filter housing.

6Replace the air filter cover, ensure that the particle collector is facing downwards.
