CHECKING THE OIL LEVELThe 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 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. 19).

6.If the level is low, add a small amount of oil to the oil fill hole and recheck (Fig. 20). Repeat this procedure until the oil level reaches the top of the dipstick.
NOTE: Do not overfill the unit.

CHANGING THE OILFor 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.
