Maintenance
Changing/Draining Oil
1. Start the engine and let it run five minutes. This
warms the oil so it drains better.
2. Park the machine so that the drain side is slightly
lower than the opposite side to assure the oil
drains completely. Disengage the power take off
(PTO), set the parking brake, and turn the
ignition key to "OFF" to stop the engine.
Remove the key.
3. Place a pan below the oil drain. Remove the oil
drain plug (Fig. 27).
4. When oil has drained completely, install the
drain plug.
Note: Dispose of the used oil at a certified
recycling center.

5. Slowly pour approximately 80% of the specified
amount of oil specified, page 41, into the filler
cap (Fig. 26). Now check the oil level; refer to
Checking Oil Level, page 41. Slowly add
additional oil to bring to "FULL" mark on
dipstick.

Change Oil Filter
Replace the oil filter every 200 hours or every other
oil change.
Note: Change oil filter more frequently when
operating conditions are extremely
dusty or sandy.
1. Drain the oil from the engine; refer to
Changing/Draining Oil, page 42.
2. Remove the old filter and wipe the filter adapter
(Fig. 28) gasket surface.
3. Pour new oil of the proper type in through the
center hole. Stop pouring when the oil reaches
the bottom of the threads. Allow a minute or two
for the oil to be absorbed by filter material.
4. Apply a thin coat of new oil to the rubber gasket
on the replacement filter (Fig. 28).

adapter. Turn the oil filter clockwise until the
rubber gasket contacts the filter adapter, then
tighten the filter an additional 1/2 turn (Fig. 28).

oil; refer to Changing/Draining Oil, page 42.
