MAINTENANCE

Replacing the air filter

If the engine seems to lack power or goes irregu- larly the reason may be that the air filter is clogged.

It is therefore important to replace the air filter at regular intervals (see maintenance schedule on page 19 for correct service interval).

The air filter is replaced as follows:

1.Raise the engine cover as described on page 20.

2.Remove the air filter housing’s plastic cover by releasing the wing-nut.

3.Remove the wing-nut on the air filter and lift off the paper filter with pre-filter.

4.Pull off the foam plastic pre-filter from the paper filter and wash clean in mild detergent.

Squeeze it dry in a clean cloth.

Drench it with new engine oil. Wrap the filter in an absorbent cloth and squeeze out excess oil.

Replace the paper filter if it is clogged with dirt.

IMPORTANT INFORMATION

Do not use compressed air to clean the paper filter.

5.Fit the air filter as follows:

Push the pre-filter over the paper filter.

Fit the paper filter with pre-filter in the air filter housing and tighten the wing-nut.

Replace the plastic cover oven the air filter housing and tighten the wing-nut.
