Changing the 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.
1. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Place a pan below the oil drain. Rotate the oil drain
valve to allow oil to drain (Fig. 42).

Note: Dispose of the used oil at a certified recycling
center.
5. Slowly pour approximately 80% of the specified oil
into the filler cap (Fig. 41). Refer to Servicing the
Engine Oil, page 34.
6. Check the oil level; refer to Checking the Oil Level,
page 34.
7. Slowly add additional oil to bring it to the full mark.

Change the Oil Filter

Replace the oil filter every 200 hours or every other oil
change.
Note: Change the 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 35.
2. Remove the old filter and wipe the filter adapter
(Fig. 43) 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. 43).
