Change the oil as follows (see Figure 8):
1. To keep dirt, grass clippings, etc., out of the
engine, clean the area around the oil fill cap/
dipstick before removing it.
2. Remove the oil drain plug and oil fill cap/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 4. Always check the level with the dipstick
before adding more oil.
5. Reinstall the oil fill cap or plug and tighten
securely.
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.
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 4.) 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.
Change Oil and Oil Filter
Change Oil
Change oil after every
100 hours
of operation. Refill
with service class SG, SH, SJ or higher oil as specified
in the Viscosity Grades table (Figure 2) on page 4.
Change the oil while the engine is still warm. The oil
will flow more freely and carry away more impurities.
Make sure the engine is level when filling, checking, or
changing the oil.
