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.
Servicing the Air Cleaner
Service Interval: Before each use or daily
Every 400 hours
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 (Figure 50) 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
(Figure 50). Clean the inside of the air cleaner cover.

2. Before removing the filter (Figure 51), 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 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 (Figure 52). Replace the safety filter with a
new one after every three primary filter services.

4. Clean the dirt ejection port located in the removable
cover. Remove the rubber outlet valve from the
cover, clean the cavity and replace the outlet valve.
