Servicing the Air Cleaner
Primary Filter: Clean or replace after every 200
operating hours.
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

3. Clean the inside of the air cleaner cover with
compressed air.
4. Gently slide the primary filter out of the air cleaner
body (Figure 3). Avoid knocking the filter into the
side of the body. Do not remove the safety filter,
unless you intend to replace it as well.
5. 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.
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. Blow
compressed air from the inside to the outside of the
primary filter.
Do not exceed 100 psi and keep the
hose at least 2 inches from the filter. Replace air filters
if they are damaged or cannot be cleaned.
Do not clean safety filter. Replace it after
600 operating hours.
