Servicing the Air Cleaner

Primary Filter: Replace every 250 operating hours or
when Filter Minder reaches Change Filter level.
Safety Filter: Replace after every 600 operating hours.
Note: Service the air cleaner more frequently if operating
conditions are extremely dusty or sandy.
Using the Filter Minder
This machine contains an air cleaner Filter Minder
gauge.
Filter Minder: Check this daily.
The plunger inside the gauge canister will change to red
when the air cleaner element becomes dirty and restricted.
When it changes red, air cleaner maintenance is required.
1. Start by visually checking the condition of the primary
element. If the element is visually dirty, replace the
primary element. Do not attempt to clean it.

point (Fig. 39).

3. Test run the engine and recheck the gauge. If the
plunger changes to red, the primary element is
restricted and must be replaced, even though it may
not appear to be dirty.
4. The gauge may be reset at any time, however it will
return to red if correct filter servicing has not been
performed.
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. Release the latches on the air cleaner and pull the air
cleaner cover off of the air cleaner body (Fig. 40).
4. Clean the inside of the air cleaner cover with
compressed air.
5. Gently slide the primary filter out of the air cleaner
body (Fig. 40). Avoid knocking the filter into the side
of the body.
6. 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.
