General Air Cleaner
Maintenance
• Check the air cleaner body for damage which could
cause an air leak. Replace if damaged. Check the whole
intake system for leaks, damage or loose hose clamps.
• Service the air cleaner filter only when the service
indicator requires it. Changing the air filter before it is
necessary only increases the chance of dirt entering the
engine when the filter is removed
• Be sure the cover is seated correctly and seals with the
air cleaner body.
Servicing the Air Cleaner
Check the air cleaner body for damage which could
possibly cause an air leak. Replace a damaged air cleaner
body.
Service the air cleaner filters when the air cleaner indicator
(Fig. 43) shows red or every 400 hours (more frequently in
extremely dusty or dirty conditions). Do not over-service
the air filter.
Be sure that the cover is sealing around the air cleaner
body.
1. Pull the latch outward and rotate the air cleaner cover
counterclockwise. Remove the cover from the body
(Fig. 43). Clean the inside of the air cleaner cover.

2. Before removing the filter (Fig. 44), 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. 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.
Important
Never attempt to clean the safety filter
(Fig. 45). Replace the safety filter with a new one after
every three primary filter services.
