Checking the Oil Level
1. Park the machine on a level surface, disengage
the blade control switch, stop the engine, and
remove the key.
2. Disengage the blade control switch and move
the control levers to the neutral locked position
and apply the parking brake.
3. Clean around the oil dipstick (Figure 21) so
that dirt cannot fall into the fill hole and
damage the engine.
4. Unscrew the oil dipstick and wipe the metal
end clean (Figure 21).

5. 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.
