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 it to cool.
2. Place the unit upright on a at, 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 ll
plug / dipstick before removing it.
4. Remove the oil ll plug/dipstick and wipe o
oil. Reinsert it all the way back in.
5. Remove the oil ll plug/dipstick and check the
oil level. Oil should be between the add and ll
marks (Fig. 15).
6. If the level is low, add a small amount of oil to
the oil ll hole (Fig. 16) and recheck. Repeat this
procedure until the oil level reaches the full mark
of the dipstick.
NOTE: Make sure the O-Ring is in place on the oil
ll plug/dipstick when checking and changing the
oil. Do not overll the unit.
