Maintenance - Remington RM4HB Operator's Manual

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.
WARNING:
Wear protective clothing and observe all
safety instructions to prevent serious personal injury.
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.
NOTE: Failure to keep the engine level may result in oil overfill.
3. Clean the area around the oil fill plug (Fig. 10) 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. 11). If the oil level is too low, add oil. Refer to Adding Oil.
Adding Oil
1. Add oil to the oil fill hole until the oil level touches the bottom
thread of the oil fill hole (Fig. 11).
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.
2. Wipe up any oil that may have spilled.
3. Make sure the O-ring is in place on the oil fill plug (Fig. 10).
4. Reinstall the oil fill plug.
