Service Interval: Every 250 hours—Replace the
primary air filter.

secondary air filter.
Note: Service the air cleaner more frequently if
operating conditions are extremely dusty or sandy.
Removing the Filters
1. Disengage the PTO, move the motion control levers
to the neutral locked position and set the parking
brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Push down to release the retaining clamps on the air
cleaner and pull the air cleaner cover off of the air
cleaner body (Figure 43).
4. Clean the inside of the air cleaner cover with
compressed air.
5. Gently slide the primary filter out of the air cleaner
body (Figure 43). Avoid knocking the filter into the
side of the body.
6. Remove the secondary filter only if you intend to
replace it.
Important: Never attempt to clean the
secondary filter. If the secondary filter is dirty,
then the primary filter is damaged and you
should replace both filters.
7. Inspect the primary filter for damage by looking into
the filter while shining a bright light on the outside
of the filter. Holes in the filter will appear as bright
spots. If the filter is damaged discard it.

operate the engine with both air filters and cover
installed.

damage. Do not use a damaged filter.

slide it into the filter body (Figure 43).

filter (Figure 43). Ensure that it is fully seated by
pushing on the outer rim of the filter while installing
it.
Important: Do not press on the soft inside area
of the filter.
