Engine Maintenance
Changing the Engine Oil and
Filter
Service Interval:
After the first 8 hours
Every 50 hours
Change the oil and filter initially after the first 8 hours of
operation; thereafter change the oil and the filter every
50 hours.
1. Park the machine on a level surface and turn the
engine off.
2. Remove the drain plug (Figure 16) and let oil flow
into a drain pan. When the oil stops, install the drain
plug.
Figure 16
3. Remove the oil filter (Figure 16). Apply a light coat
of clean oil to the new filter gasket.
4. Screw the filter on by hand until the gasket contacts
the filter adapter; then tighten 1/2 to 3/4 turn
further. Do not overtighten.
5. Add oil to the crankcase; refer to Checking the
Crankcase Oil.
6. Dispose of used oil properly.
Servicing the Remote Air
Cleaner
•
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 every 200 hours 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 the filter is removed.
•
Be sure the cover is seated correctly and seals with
the air cleaner body.
Replacing the Air Filter
Service Interval:
Every 200 hours
1. Release the latches securing the air cleaner cover to
the air cleaner body (Figure 17).

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.
Important:
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 filter.
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.
Note:
Cleaning of the used element is not
recommended due to the possibility of damage to
the filter media.
4. Clean the dirt ejection port located in the removable
cover. Remove the rubber outlet valve from the
cover, clean the cavity and replace the outlet valve.
