Engine Maintenance
Engine Safety
•
Shut off the engine before checking the oil or
adding oil to the crankcase.
•
Do not change the governor speed or overspeed
the engine.
Servicing the Air Cleaner
Service Interval: Every 200 hours (more frequently in
extremely dusty or dirty conditions).
•
Check the air-cleaner body for damage which
could cause an air leak. Replace it if it is damaged.
Check the whole intake system for leaks, damage,
or loose hose clamps.
•
Service the air cleaner at the recommended
service interval or earlier if engine performance
suffers due to extremely dusty, dirty conditions.
Changing the air filter before it is necessary only
increases the chance of dirt entering the engine
when you remove the filter.
•
Be sure that the cover is seated correctly and
seals with the air-cleaner body.
1. Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key.
2. Release the latches securing the air-cleaner
cover to the air-cleaner body (
Figure 54 ).
3. Remove the cover from the air-cleaner body
(
Figure 54 ).
4. Before removing the filter, use low-pressure air
(276 kPa [40 psi], clean and dry) to help remove
large accumulations of debris packed between
outside of primary filter and the canister.
Note:
Avoid using high-pressure air, which
could force dirt through the filter into the intake
tract. This cleaning process prevents debris
from migrating into the intake when you remove
the primary filter.
5. Remove and replace the filter ( Figure 54 ).
Do not clean the used element because it could
damage the filter media.

6. Inspect the new filter for shipping damage,
checking the sealing end of the filter and the
body.
Important:
Do not use a damaged element.
7. Insert the new filter by applying pressure to the
outer rim of the element to seat it in the canister.
Important:
Do not apply pressure to the
flexible center of the filter.
8. Clean the dirt-ejection port located in the
removable cover.
9. Remove the rubber outlet valve from the cover,
clean the cavity and replace the outlet valve.
10. Install the cover orienting the rubber outlet valve
in a downward position—between approximately
5 o’clock to 7 o’clock when viewed from the end.
11. Secure the cover latches.
Changing the Engine Oil
and Filter
Service Interval: After the first 50 hours
Every 150 hours
1. Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key.
2. Remove either drain plug ( Figure 55 ) and let
the oil flow into a drain pan. When the oil stops
flowing, install the drain plug.
