WARNING:
To avoid serious personal injury, always
stop the engine and allow it to cool before cleaning
or maintaining the unit. Never perform cleaning or
maintenance while the unit is running. Disconnect
the spark plug wire to prevent the unit from starting
accidentally.

safety instructions to prevent serious personal injury.
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 result in oil overfill.
3. Clean the area around the oil fill plug (Fig. 11) 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. Add oil
to the oil fill hole until the oil level is visible on the first
thread of the oil reservoir (Fig.10). 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. 9).
