2. Remove the cover from the air cleaner body. Before
removing the filter, use low pressure air (40 psi,
clean and dry) to help remove large accumulations
of debris packed between outside of primary filter
and the canister. Avoid using high pressure air which
could force dirt through the filter into the intake
tract. This cleaning process prevents debris from
migrating into the intake when the primary filter is
removed.
3. Remove and replace the primary filter (Figure 39).
Cleaning of the used element is not recommended
due to the possibility of damage to the filter media.
Inspect the new filter for shipping damage, checking
the sealing end of the filter and the body. Do not use
a damaged element. Insert the new filter by applying
pressure to the outer rim of the element to seat it in
the canister. Do not apply pressure to the flexible
center of the filter.

cover, clean the cavity and replace the outlet valve.
