Check Oil Level
The importance of checking and maintaining
the proper oil level in the crankcase cannot be
overemphasized. Check oil BEFORE EACH USE as
follows:
1. Make sure the engine is stopped, level, and is
cool so the oil has had time to drain into the
sump.
2. Clean the area around and beneath the dipstick
or the oil fi ll plug before removing it. This will
help keep dirt, debris, and other foreign ma er
out of the engine. See Figure 6-3.

3. Checking oil level with a dipstick. Unscrew and
remove the dipstick; wipe off oil. Reinsert the
dipstick into the oil fi ll tube and rest the dipstick
on the oil fi ll tube. Turn it counterclockwise until
the cap drops down to the lowest point of the
thread leads. Do not thread the dipstick cap into
the tube. See Figure 6-5.

4. If the level is low, add oil of the proper type
(Refer to Oil Type) to the correct level. Always
check the level before adding more oil. See
Figures 6-5 and 6-6.
NOTE: To prevent extensive engine wear or
damage, always maintain the proper oil
level in the crankcase. Never operate the
engine with the oil level above or below
the correct level.
