CHECKING THE OIL LEVEL

WARNING:
OVERFILLING THE CRANKCASE MAY
CAUSE SERIOUS PERSONAL INJURY. Check the oil level
before each use. The importance of maintaining the proper
oil level cannot be overemphasized.
1. Stop the engine and allow it to cool.
2. Set the unit on a flat, level surface, such as a workbench or
table.
NOTE: Failure to keep the engine level may cause the oil to overfill.
3. Clean the area around the oil fill plug (Fig. 19) to prevent debris
from entering the oil fill hole.
4. Unscrew the oil fill plug.
5. Look into the oil fill hole; use a flashlight if necessary. The oil
level should just touch the bottom thread of the oil fill hole
(Fig. 20). If the oil level is too low, add oil to the oil fill hole until
the oil level touches the bottom thread of the oil fill hole.
NOTE: DO NOT overfill the crankcase.
6. Wipe up any oil that may have spilled.
7. Reinstall the oil fill plug.
NOTE: Make sure the O-ring is in place on the oil fill plug (Fig. 19).
