Engine Maintenance
Servicing the Air Cleaner
Service Interval: Before each use or daily—Check the
air-filter-service indicator.
Every 25 hours—Remove the air-cleaner cover, clean
out debris, and check the air-filter-service indicator.
Servicing the Air-Cleaner Cover
and Body
Important:
Replace the air-cleaner filter only when the
service indicator shows red ( Figure 43 ). Changing the
air filter before it is necessary only increases the chance
of dirt entering the engine when you remove the filter.
1. Park the machine on a level surface, engage the parking
brake (if equipped), and lower the loader arms.
2. Shut off the engine and remove the key.
3. Open the hood and secure the prop rod (if applicable).
4. Check the air-cleaner body for damage that could cause
an air leak. Check the whole intake system for leaks,
damage, or loose hose clamps.
Replace or repair any damaged components.
5. Release the latches on the air cleaner and pull the
air-cleaner cover off the air-cleaner body (
Figure 43 ).
Important:
Do not remove the air filter.

•
If the service indicator is clear, install the air-cleaner
cover with the dust cap oriented downward and
secure the latches (
Figure 43 ).
•
If the service indicator is red, replace the air filter
as described in
Replacing the Filter (page 30) .
Replacing the Filter
Important:
To prevent engine damage, always operate
the engine with the air filter and cover installed.
1. Gently slide the filter out of the air-cleaner body
(
Figure 43 ).
Note:
Avoid knocking the filter into the side of the
body.
Important:
Do not attempt to clean the filter.
2. Inspect the new filter for tears, an oily film, or damage
to the rubber seal. Look into the filter while shining
a bright light on the outside of the filter; holes in the
filter appear as bright spots.
If the filter is damaged, do not use it.
3. Carefully install the filter ( Figure 43 ).
Note:
Ensure that the filter is fully seated by pushing
on the outer rim of the filter while installing it.
Important:
Do not press on the soft inside area
of the filter.
4. Install the air-cleaner cover with the dust cap oriented
downward and secure the latches (
Figure 43 ).
5. Close the hood.
