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.
2.Place the unit on a flat,
level surface to get a
proper oil level reading (Fig. 5).
3. Keep dirt, grass clippings
and other debris out of the engine. Clean the area around the dipstick before
removing it.
4. Remove the oil fill plug/dipstick and wipe off oil. Reinsert it all the
way back in.
5. Remove the oil fill plug/ dipstick and check the oil
level. Oil should be up to the top of the dipstick (Fig. 23).
6.If the level is low, add a small amount of oil to the oil fill hole and recheck (Fig. 24). Repeat this procedure until the oil level reaches the top of the dipstick.
NOTE: Do not overfill the unit.
NOTE: Make sure the
CHANGING THE OIL
WARNING: Wear gloves to prevent injury when handling unit.
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.
1.Unplug spark plug boot to prevent accidental starting.
2.Remove the oil fill plug/dipstick.
3. Pour the oil out of the oil fill hole and into a container by tipping the unit to a vertical position (Fig. 25). Allow ample time for complete drainage.
4.Wipe up any oil residue
on 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 |

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. 26). Check the level with the dipstick. If the level is low, add a small amount of oil and recheck. Do not overfill (Fig. 26).
