Replacing The Air Filter Pro 18 - Husqvarna Rider Pro 18 Operator's Manual

Replacing the air filter Pro 18

If the engine seems to lack power or does not run
smoothly this may be because the air filter is
clogged. If run with a soiled air filter, carbon can
build-up on the spark plugs and lead to
malfunctioning.
It is therefore important to replace the air filter at
regular intervals (see "Maintenance schedule" for
correct service interval).
WARNING!
Let the muffler system cool down
before carrying out service work.
Otherwise there is a risk of burns.
Clean/ replace the air filter as follows:
1. Release the rubber strap under the seat and
raise the engine hood.
IMPORTANT INFORMATION
Never run the engine without the muffler
fitted.
Do not use compressed air to clean the
paper filter. Do not wash the paper filter.
The filters must not be oiled. They must be
fitted dry.
2. Fold out the two snap-locks and lift off the cover
on the air filter housing.
3. 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.
4. Unscrew the wing nut from the air filter and lift
out the paper filter. Tap the filter against a hard
surface to shake off the dust. If the paper filter is
still dirty it should be replaced.
5. Refit the air filter as follows:
Insert the paper filter in the air filter housing and
tighten the wing nut.
6. Fit the pre-filter over the rectangular section of
the paper filter.
7. Refit the cover on the air filter housing. Bring up
the cover from below and make sure the pre-
filter does not drop out of place. Secure with the
two clips.
