Checking the Oil Level
1. Park the machine on a level surface.
2. Disengage the blade control (PTO).
3. Stop the engine, wait for all moving parts to stop, and
remove the key before leaving the operating position.
4. Clean around the oil dipstick (Figure 29) so that dirt
cannot fall into the fill hole and damage the engine.
1. Oil dipstick/fill hole
5. Unscrew the oil dipstick and wipe the end clean.
6. Screw the oil dipstick fully onto the fill hole.
7. Unscrew the dipstick again and look at the end. If
the oil level is low, slowly pour only enough oil into
the fill hole to raise the level to the Full mark on the
dipstick.
Important: Do not overfill the crankcase with
oil and run the engine; engine damage may
result.
Changing the Oil
Service Interval: After the first 5 hours
Every 100 hours

lower than the left side to ensure that the oil drains
completely.

3. Stop the engine, wait for all moving parts to stop, and
remove the key before leaving the operating position.
