Greasing the Generator Belt
Tensioner
Service Interval: Every 400 hours
Lubricate the grease fitting regularly with No. 2 General
Purpose Lithium-Base Grease.

be forced into the bearing or bushing (Figure 43).
Figure 43
The grease fitting is located behind the seat on the inner,
right side of the machine.
2. Pump grease into the bearing or bushing until the
grease is visible. Wipe up excess grease.

Engine Maintenance

Servicing the Air Cleaner

Service Interval: Every 200 hours
•
Check the air cleaner body for damage which could cause
an air leak. Replace if damaged. Check the whole intake
system for leaks, damage or loose hose clamps.
•
Service the air cleaner filter before 200 hours if the
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
the filter is removed.
•
Be sure the cover is seated correctly and seals with the
air cleaner body.
1. Release the latches securing the air cleaner cover to the
air cleaner body (Figure 44).

2. Remove the cover from the air cleaner body. Before
removing the filter, use low pressure air (40 psi, clean
and dry) to help remove large accumulations of debris
packed between outside of primary filter and the
canister. 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 the primary filter is removed.
3. Remove and replace the primary filter. Cleaning of the
used element is not recommended due to the possibility
of damage to the filter media. Inspect the new filter for
shipping damage, checking the sealing end of the filter
and the body. Do not use a damaged element. Insert
the new filter by applying pressure to the outer rim of
the element to seat it in the canister. Do not apply
pressure to the flexible center of the filter.
