CHECKING THE OIL LEVEL

such as a
workbench or table.
Note:
Failure to keep the engine level may result in oil
overfill.

debris from entering the oil fill hole.

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

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.
