Checking the Oil Level
1. Park the machine on a level surface, disengage the PTO,
stop the engine, and remove the key.
2. Clean around the oil dipstick (Fig. 19) so that dirt
cannot fall into the fill hole and damage the engine.

4. Screw the oil dipstick fully onto the fill hole. Unscrew
the dipstick, pull it out, and look at the metal end. If the
oil level is low, slowly pour only enough oil into the fill
hole to raise the level to, but not over, the Full mark on
the dipstick.
Important
Do not overfill the crankcase with oil
because the engine may be damaged.
Changing and Draining 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.
