3. Clean the area around the oil fill plug (Fig. 19) to prevent debris
from entering the oil fill hole.

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. 20). If the oil level is too low, add oil to the oil fill hole until

before each use. The importance of maintaining the proper
oil level cannot be overemphasized.
