Checking the Engine Oil Level
Before you use the lawn mower, make sure that the oil level is between the Upper and the Lower Limit
marks as shown on the dipstick. If the oil level is below the Lower Limit mark, add oil.
Cleaning the Underside of the Lawn Mower Housing
To ensure the best performance, keep the underside of the lawn mower housing clean.
1. Disconnect the spark plug wire and drain the fuel tank.
2. Tip the lawn mower onto its left side with the carburetor and air cleaner on the upside of the
mower and away from the ground. Remove the grass thoroughly and return the mower to up-
right position.
