CHECKING THE OIL LEVEL

The importance of checking and maintaining the proper oil level in the crankcase cannot be overemphasized. Check oil before each use:

1.Stop the engine and allow oil to drain into the crankcase.

CAUTION: To prevent extensive engine wear and damage to the unit, always maintain the proper oil level in the crankcase. Never operate the unit with the oil level below the bottom of the dipstick.

2.Place the unit on a flat, level surface to get a proper oil level reading.

3.Keep dirt, grass clippings and other debris out of the engine. Clean the area around the oil fill plug/dipstick before removing it.

4.Remove the oil fill Oil Fill Plug/Dipstick

NOTE: Do not overfill the unit.

NOTE: Make sure the O-ring is in place on the oil fill plug/dipstick when checking and changing the oil (Fig. 22).

CHANGING THE OIL

For a new engine, change the oil after the first 10 hours of operation. Change the oil while the engine is still warm. The oil will flow freely and carry away more impurities.

CAUTION: Wear gloves to prevent injury when handling the unit.

and clean up any oil that may have spilled. Dispose of the oil according to Federal, State and local regulations.

5.Refill the crankcase with 3.04 fluid ounce (90 ml) of SAE 30 SF, SG, SH oil.

NOTE: Use the bottle and spout saved from initial use to measure the correct amount of oil. The top of the label on the bottle measures approximately 3.04 ounces (90 ml) (Fig. 24).

Check the level with the dipstick. If the level is low, add a small amount of oil and recheck. Do not overfill (Fig. 24).

6.Replace the oil fill plug/dipstick.

7.Reconnect the spark plug boot.
