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 Window
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. 34).
NOTE: Failure to keep the engine level may result in oil overfill.
3. Look into the oil level window; use a flashlight if necessary. The
oil level should fill the window approximately halfway (Fig. 35).
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. 35) 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 approximately
halfway up the oil level window (Fig. 35).
WARNING:
DO NOT overfill the crankcase.
OVERFILLING THE CRANKCASE MAY CAUSE SERIOUS
PERSONAL INJURY.
• 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. 35).
6. Reinstall the oil fill plug.
CHANGING THE OIL
Change the oil while the engine is still warm. The oil will flow freely
and carry away more impurities.
1. Clean the area around the oil fill plug (Fig. 35) to prevent debris
from entering the oil fill hole.
2. Unscrew the oil fill plug.
3. Tip the unit vertically to pour the oil out of the oil fill hole and into
a container (Fig. 36). Allow ample time for complete drainage.
NOTE: Dispose of the old oil according to federal, state and local
regulations.
4. Wipe up any oil that may have spilled.
5. Pour 2.37 fl.oz. (70 ml) of SAE 30 oil into the oil fill hole.
WARNING:
DO NOT overfill the crankcase.
OVERFILLING THE CRANKCASE MAY CAUSE SERIOUS
PERSONAL INJURY. Refer to Checking the Oil Level.
6. Wipe up any oil that may have spilled.
7. Make sure the O-ring is in place on the oil fill plug (Fig. 35).
8. Reinstall the oil fill plug.
