Checking Oil Level
1.
Park the machine on a level surface, disengage
the power take off (PTO) and turn the ignition
key to "OFF" to stop the engine. Remove the
key.
2.
Clean around the oil dipstick (Fig. 27) so dirt
cannot fall into the filler hole and damage the
engine.
3.
Unscrew the oil dipstick and wipe the end clean
(Fig. 27).
4.
Slide the oil dipstick fully into the filler tube, do
not thread onto tube (Fig. 27). Pull the dipstick
out and look at the 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.
