Changing the Oil

1. Start the engine and let it run for five minutes. This

warms the oil so it drains better.

2. Park the traction unit so that the drain side is slightly

lower than the opposite side to ensure that the oil
drains completely.

3. Lower the loader arms, chock the wheels, and stop the

engine. Remove the key.

Components will be hot if the traction unit has
been running.  If you touch hot components you
may be burned.

Allow the traction unit to cool before performing
maintenance or touching components under the
hood.

Caution

4. Place a pan under the oil drain tube (Fig. 25).

5. Loosen the clamp and remove the plug (Fig. 25).

6. When the oil has drained completely, replace the plug

and tighten the clamp.

Note: Dispose of the used oil at a certified recycling
center.

Changing the Oil Filter

Replace the oil filter every 150 hours or every other oil
change.

Note: Change the oil filter at each oil change when
operating conditions are extremely hot, dusty, or sandy.

1. Drain the oil from the engine; refer to Changing the

Oil, page 25.

2. Open the rear access cover; refer to Opening the Rear

Access Cover, page 23.

3. Remove the old filter and wipe the filter adapter

(Fig. 26) gasket surface.

filter material, then pour off the excess oil.

5. Apply a thin coat of new oil to the rubber gasket on

the replacement filter (Fig. 26).
