Replacing 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:
1 Open the engine cover.
2 Loosen the knobs holding the filter cover in place and
remove it.
3 Remove the air filter cover.
4 Lift out the air filter cartridge from the fan housing.
5 Remove the foam rubber prefilter which is placed around
the filter cartridge and clean using a mild detergent.
Dry the pre-filter properly.
IMPORTANT INFORMATION
Do not use compressed air to clean the paper filter.
Do not oil the paper filter. They must be fitted dry.
6 Refit the prefilter on the filter cartridge.
7 Slide the filter onto the air hose.
8 Push the filter cartridge in place.
9 Refit the air filter cover.
Maintenance
Replacement of fuel filter

season) or more frequently if it is clogged.

2 Remove the protective cover by unscrewing the screws.
3 Move the hose clips away from the filter. Use a pair of flat
pliers.
4 Pull off the filter from the hose ends.
