Engine Maintenance
Servicing the Air Cleaner
Service Interval: Every 200 hours (More frequently in
extreme 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.
