Engine Maintenance

Servicing the Air Cleaner

Primary Filter: Replace every 250 operating hours
or when Filter Minder reaches the 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 pressing the button in the
bottom of the canister until the plunger returns
to the lowest point (Figure 36).

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.

will return to red if correct filter servicing has
not been performed.
