Servicing the Air Cleaner

Primary Filter: Clean or replace every 200 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.
2. Reset the gauge by depressing the button in the bottom
of the canister until the plunger returns to the lowest
point (Fig. 35).
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.

the filter while shining a bright light on the outside of
