Changing the Engine Oil and
Filter
Service Interval: After the first 50 hours
Every 100 hours
Change the oil after the first 50 operating hours.
Thereafter, under normal conditions, change the oil and
the filter after every 100 hours of operation. However,
an engine operated in dusty or dirty conditions requires
more frequent oil changes. If possible, run the engine
just before changing the oil. Warm oil flows more freely
and carries more contaminants than cold oil.
1. Position the machine on a level surface.
2. Disengage the hood latches and open the hood.
3. Place an oil drain pan below the drain hose on the
side of the crankcase (Figure 23).
4. Rotate the drain valve counter clockwise and allow
the oil to flow into a drain pan. After the oil has
drained, rotate the oil drain valve clockwise.
5. Remove the oil filter (Figure 23) and discard it.
Thoroughly clean the filter mounting surface and
make sure that a new gasket is installed in the new
filter.

6. Apply a thin film of clean oil to the gasket. Install a
new filter by hand until the gasket just touches the
mounting surface, then turn the filter an additional
1/2 to 3/4 turn.
7. Remove the filler cap (Figure 24) and pour
approximately 2 quarts of oil into the filler neck.

8. Start the engine and check for leaks around the oil
filter. Tighten the filter only enough to eliminate
leaks. Do not overtighten.
9. Turn off the engine and allow the machine to stand
for 2 minutes.
10. Check the oil and make sure that the level is up to
the FULL mark on the dipstick. Add more oil if the
level is low; however, do not overfill.
11. Lower the hood and secure the latches.
General Air Cleaner
Maintenance
Service Interval: Every 200 hours
1. 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.
2. 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.
3. Be sure the cover is seated correctly and seals with
the air cleaner body.
Servicing the Air Cleaner
The primary air cleaner element must be checked
and/or replaced after every 200 hours of engine
operation. However, the air cleaner must be cleaned
more frequently if operating conditions are extremely
dusty or sandy.
1. Release the latches securing the air cleaner cover to
the air cleaner body (Figure 25).
