Checking the Oil Level
1. Park the machine on a level surface, disengage the
power take off (PTO), set the parking brake, and turn
the ignition key to off. Remove the ignition key.
2. Open the hood.
3. Clean around the oil dipstick (Fig. 20) so dirt cannot
fall into the filler hole and damage the engine.
4. Unscrew the oil dipstick and wipe the metal end clean
(Fig. 20).
5. Slide the oil dipstick fully into the filler tube, do not
thread onto tube (Fig. 20). Pull the dipstick out and
look at the metal end. If oil level is low, slowly pour
only enough oil into the filler tube to raise the level to
the full mark.
Important Do not overfill the crankcase with oil
because the engine may be damaged.
