Engine Maintenance

Servicing the Air Cleaner

Clean the primary filter every 25 operating hours.
Replace the primary and secondary filter yearly.
Note: Service the air cleaner more frequently if
operating conditions are extremely dusty or sandy.
Removing the Filters
1. Lower the loader arms and stop the engine.
Remove the key.
2. Open the rear access cover.
3. Release the latches on the air cleaner and pull
the air cleaner cover off of the air cleaner body
(Figure 25).

4. Clean the inside of the air cleaner cover with
compressed air.
5. Gently slide the primary filter out of the air
cleaner body (Figure 25). Avoid knocking the
filter into the side of the body. Do not remove
the safety filter, unless you intend to replace
it as well.
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; otherwise, clean 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.
Cleaning the Primary Filter
Blow compressed air from the inside to the outside
of the primary filter.
Important: Do not exceed 100 psi (689 kPa)
and keep the hose at least 2 inches (5 cm)
from the filter.
Installing the Filters
1. If installing new filters, check each filter for
shipping damage. Do not use a damaged filter.
2. If the safety filter is being replaced, carefully
slide it into the filter body (Figure 25).
