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.
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.
NOTE: Make sure the O-ring is in place on the oil fill plug/dipstick
when checking and changing the oil (Fig. 20).
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:
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.
