Servicing the Air Cleaner
Primary Filter: Check and/or replace after every 200
operating hours or more often in dusty conditions.
Safety Filter: Replace after every 600 operating hours.
Note: Check the filters more frequently if operating
conditions are extremely dusty or sandy.
Removing the Filters
1. Disengage the power take off (PTO), set the parking
brake, and turn the ignition key to off. Remove the
key. Remove spark plug wire(s).
2. Release the latches on the air cleaner and pull the air
cleaner cover off of the air cleaner body (Fig. 36).
3. Clean the inside of the air cleaner cover with
compressed air.
4. Gently slide the primary filter out of the air cleaner
body (Fig. 36). Avoid knocking the filter into the side
of the body.
5. Remove the safety filter only if you intend to replace
it.
Important Never attempt to clean the safety filter. If
the safety filter is dirty, then the primary filter is damaged
and you should replace both filters.
6. 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.
