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.
Caution
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.
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.
