Engine Maintenance
Servicing the Air Cleaner
Service Interval: Every 200 hours—Change the air
cleaner filter. (more frequently in
dusty or dirty conditions)
Inspect the air cleaner and hoses periodically to maintain
maximum engine protection and to ensure maximum
service life. Check the air cleaner body for damage
which could possibly cause an air leak. Replace a
damaged air cleaner body.
Inspect and change the air cleaner filter as described in
the following procedure:
1. Pull the latch outward and rotate the air cleaner
cover counterclockwise.

2. Before removing the filter, use low pressure
air (40 psi, clean and dry) to help remove large
accumulations of debris packed between the outside
of the primary filter and the canister.
Important: 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.
Note: Cleaning of the used element is not
recommended due to the possibility of damage to
the filter media.
4. Inspect the new filter for shipping damage, checking
the sealing end of the filter and the body.
Important: Do not use a damaged element.

5. Insert the new filter by applying pressure to the outer
rim of the element to seat it in the canister.
6. 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.
7. Install the cover orienting the rubber outlet valve in
a downward position—between approximately 5:00
to 7:00 when viewed from the end.
8. Secure the cover latches. Reset the indicator if it is
showing red (if so equipped).
