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. To keep dirt, debris, etc., out of the engine, clean
the area around the dipstick before removing it.
3. Remove the dipstick; wipe oil off. Reinsert the
dipstick into the tube and press all the way
down.
4. Remove the dipstick and check the oil level.
The oil level should be up to, but not over, the “F”
mark on the dipstick. See Figure 7.
5. If the level is low, add oil of the proper type, up to
the “F” mark on the dipstick. (Refer to Oil Type on
page 5.) Always check the level with the dipstick
before adding more oil.
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 below the “L”
mark or over the “F” mark on the
dipstick.
Oil Sentry™
Some engines are equipped with an optional Oil
Sentry™ oil pressure switch. If the oil pressure
decreases below an acceptable level, the Oil Sentry™
will either shut off the engine or activate a warning
signal, depending on the application.
NOTE: Make sure the oil level is checked BEFORE
EACH USE and is maintained up to the “F”
mark on the dipstick. This includes engines
equipped with Oil Sentry™.
