an absorbent cloth and squeeze out excess oil.

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.
IMPORTANT INFORMATION
Do not use compressed air to clean the
paper filter.
