Replacing The Air Filter - Husqvarna Rider ProFlex 21 II Operator's Manual

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. If run with a soiled air filter,
carbon can build-up on the spark plugs and
lead to malfunction.
For this reason, it is important to replace the
air filter regularly (see Maintenance Schedule
on page 25 for the proper service interval).
Cleaning/replacement of the air filter is
carried out as follows:
!
WARNING!
Allow the exhaust system to
cool before performing service.
Risk for burns.
1. Fold up the engine cover.
2. Remove the two plastic fasteners on the
top of the air filter cover and remove the
air filter cover.
3. Remove the foam rubber pre-filter and
clean using a mild detergent.
Squeeze it dry with a clean cloth.
4. Remove the wing nuts for the air filter
and remove the paper filter. Tap the
paper filter against a fixed surface to
remove dust. If the paper filter is still
dirty, it must be replaced.
IMPORTANT INFORMATION
Do not use compressed air to clean the
paper filter.
Do not wash the paper filter.
Do not oil the paper filter.
5. Refit the air filter as follows:
Check that the seal on the bottom of the
paper filter is whole. Mount the paper
filter in the air filter housing and tighten
the wing nuts.
