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 to cool.
2. Place the unit on a fiat, 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 offoil. Rein-
sert it all the way back in.
S. Remove the oil fill plug/dipstick and check the oil level.
Oil should be between the add and fill marks (Fig. 16).
6. If the level is low, add a small amount ofoil to the oil
fill hole (Fig.17) and recheck. Repeat this procedure
until the oil level reaches the full mark of the dipstick.
NOTE: Do not overfill the unit.
