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:
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. 24).

6. If the level is low, add a small amount of oil to the oil fill
hole and recheck (Fig. 25). Repeat this procedure until the
oil level reaches the top of the dipstick.
NOTE: Do not overfill the unit.

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.
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. 26). Allow ample
time for complete drainage.
