CHECKING THE OIL LEVEL
Do not overfill engine. Too much oil may cause engine
to smoke or spark plug fouling.
Too much oil may cause smoking or allow oil to enter
the air filter enclosure.
The oil should be checked with the engine warm. The
vehicle should be on a level surface with the parking
(PARK) brake engaged. Allow adequate time for oil to
drain into the crankcase before checking.
Remove the dipstick and wipe off the entire area with a
lint free cloth.

Fig. 29 Check Oil Level on Dipstick
The engine can be operated safely as long as oil is
within the safe operating range as indicated on the dip
stick. Do not operate vehicle if oil level is below the
safe area indicated on the dipstick.
Oil should be added to bring the level into the safe oper-
ating range. Remember that oil expands as it gets hot,
Do not overfill. Check that the oil cap is firmly in place.
When adding oil between oil changes, do not mix brands and
viscosity grades of oil.
The oil dipstick/fill cap must be in place before operating
the engine. Failure to install the dipstick/fill cap will result
in oil becoming contaminated and/or oil being dis-
charged into the engine compartment.
