CHECKING THE OIL LEVEL
WARNING:
Check the oil level before each use. The importance
of maintaining the proper oil level cannot be
overemphasized.
Inspecting the Oil Level
1. Stop the engine and allow it to cool.
2. Set the unit on a flat, level surface, such as a
workbench or table. The cutting head shield should
hang over the edge so that the engine is level
(Fig. 19).
NOTE: Failure to keep the engine level may result in a
faulty oil level reading.
3. Unscrew the oil fill plug. The oil level should be visible
on the first thread of the oil reservior (Fig. 20). If the
oil level is too low, add oil. Refer to Adding Oil.
Adding Oil
1. Clean the area around the oil fill plug (Fig. 20) to
prevent debris from entering the oil fill hole.
2. Unscrew the oil fill plug.
3. Add oil to the oil fill hole until the oil level is visible on
the first thread of the oil reservoir (Fig. 20).
WARNING:
DO NOT overfill the oil level. Overfilling will result in
too much oil in the engine crankcase, and may cause
smoke or fumes that can injure the user.
• If the oil level is too high, tip the unit and drain the
excess oil into an appropriate container.
4. Wipe up any oil that may have spilled.
5. Make sure the O-ring is in place on the oil fill plug
(Fig. 21).
6. Reinstall the oil fill plug.
