Figure 7. Oil Level Dipstick.
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 monitor. 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™.

Change Oil
Change oil after every 100 hours of operation (more
frequently under severe conditions). Refill with service
class SG, SH, SJ or higher oil as specified in the
‘‘Viscosity Grades’’ table (Figure 3) on page 5.
Change the oil while the engine is still warm. The oil will
flow freely and carry away more impurities. Make sure
the engine is level when filling, checking, and changing
the oil.
Change the oil as follows (see Figures 8 and 9):
1. To keep dirt, debris, etc., out of the engine, clean
the area around the oil fill cap/dipstick before
removing it.
2. Remove one of the oil drain plugs, oil fill cap, and
dipstick. Be sure to allow ample time for complete
drainage.
3. Reinstall the drain plug. Make sure it is tightened
to 13.6 N·m (10 ft. lb.) torque.
4. Fill the crankcase, with new oil of the proper type,
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.
5. Reinstall the oil fill cap and tighten securely.
Reinstall dipstick.
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.
