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.
5. Install the cover orienting the rubber outlet valve in a
downward position - between approximately 5:00 to
7:00 when viewed from the end.
6. Reset the indicator (Figure 50) if it shows red.
