Engine Maintenance

Servicing the Air Cleaner

Replace the air cleaner filter every 250 operating
hours.
Note: Service the air cleaner filter 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. Unlatch the seat, tilt the seat up and tilt the
engine cover forward.
4. Clean around the air cleaner to prevent dirt
from getting into the engine and causing
damage. Release the latches on the air cleaner
and pull the air cleaner cover off of the air
cleaner body (Figure 36).

6. Gently slide the air filter out of the air cleaner
body (Figure 36). Avoid knocking the filter
into the side of the body.
Servicing the Air Filter
Do not clean the primary filter. Replace it after
250 hours.
Inspect the air 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.
Installing the Filters
Important: To prevent engine damage,
always operate the engine with the air filter
and cover installed.
1. If installing a new filter, check each filter for
shipping damage. Do not use a damaged filter.
2. Carefully slide the air filter into the air cleaner
body (Figure 36). Ensure that it is fully seated
by pushing on the outer rim of the filter while
installing it.
