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 or every 400 hours (more
frequently in extremely dusty or dirty conditions).
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.

1. Pull the latch outward and rotate the air cleaner
cover counterclockwise (Figure 46).
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 area.
This cleaning process prevents debris from migrating
into the intake when the primary filter is removed.

3. Remove the primary filter (Figure 47). 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. Do not remove the safety filter (Figure 48).
