How to Inspect the Engine Air

and lightly shake the filter to release
loose dust and dirt. If the filter

cleaner/filter, do the following:
1. Unhook the retainer clips and

cleaner/filter housing. Care
should be taken to dislodge as
little dirt as possible.

filter housing.
4. Inspect or replace the engine air
cleaner/filter. Make sure that the
filter fits properly into the
housing.
5. Reinstall the cover and fasten
the retaining clips.
