Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 400 hours
Check the air-cleaner body for damage which could cause an
air leak. Replace it if it is damaged. Check the whole intake
system for leaks, damage, or loose hose clamps.
Service the air-cleaner filter only when the service indicator
(Figure 33) requires it. Changing the air filter before it is
necessary only increases the chance of dirt entering the engine
when the filter is removed.

Note: Before removing the filter, use low-pressure
air (276 kPa [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
Note: Cleaning the used element is not recommended
due to the possibility of damage to the filter media.

4. Inspect the new filter for shipping damage, checking
the sealing end of the filter and the body.
Note: 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.
Important: Never attempt to clean the safety filter
(Figure 36). Replace the safety filter with a new
one after every 3 primary filter services.
