Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 200 hours (more frequently in
extremely dusty or dirty conditions).
•
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 at the recommended service
interval or earlier if engine performance suffers due to
extremely dusty, 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 that the cover is seated correctly and seals with
the air-cleaner body.
1. Release the latches securing the air-cleaner cover to the
air-cleaner body (Figure
2. Remove the cover from the air-cleaner body
53).
3. 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.
Note: 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.
4. Remove and replace the filter
Cleaning of the used element is not recommended due
to the possibility of damage to the filter media.

6. Insert the new filter by applying pressure to the outer
rim of the element to seat it in the canister.
Important: Do not apply pressure to the flexible
center of the filter.
7. Clean the dirt-ejection port located in the removable
cover.
8. Remove the rubber outlet valve from the cover, clean
the cavity and replace the outlet valve.

downward position—between approximately 5:00 to
7:00 when viewed from the end.
