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 if damaged. Check the whole intake system
for leaks, damage or loose hose clamps.
Service the air cleaner filter only when the service indicator
(
Figure 29 ) requires it. Changing the air filter before it is
necessary only increases the chance of dirt entering the engine
when the filter is removed.

Important:
Be sure the cover is seated correctly and
seals with the air cleaner body.
1. Pull the latch outward and rotate the air cleaner cover
counterclockwise (
Figure 30 ).

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 31 ).
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
( Figure 32 ). Replace the safety filter with a new
one after every three primary filter services.
