NOTE: If the engine stalls or does not start, turn the
engine switch to ‘‘on’’ position and then pull
the recoil starter or attempt to start engine. If
the oil warning light flickers for a few seconds,
the engine oil is insufficient. Add oil and
restart.
NOTE: Make sure the oil level is checked BEFORE
EACH USE and is maintained up to the point
of overflowing the filler neck.
Change Oil
For a new engine, change oil after the first 20 hours
of operation. Thereafter, change oil after every 100
hours of operation.
For an overhauled engine, use 10W-30 – weight
service class SG, SH, SJ or higher oil for the first 20
hours of operation. Change the oil after this initial run-
in period. 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 freely and carry away more impurities. Make sure
the engine is level when filling, checking, or changing
the oil.
Change the oil as follows (see Figure 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 the oil drain plug and oil fill/check plug.
Be sure to allow ample time for complete
drainage.
3. Reinstall the drain plug. Make sure it is tightened
to 17.6 N·m (13 ft. lb.) torque.
4. Fill the crankcase, with new oil of the proper type,
up to the point of overflowing the filler neck. Refer
to “Oil Type” on page 4. Always check the level
before adding more oil.
5. Reinstall the oil fill/check 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 point of
overflowing the filler neck.
NOTE: Just because you can see oil in the crankcase
doesn't mean the level is in the safe range.
Bring the level up to the point of overflowing
the filler neck.
Figure 10. Proper Oil Level.
5. If the level is low, add oil of the proper type, up to
the point of overflowing the filler neck. (Refer to
“Oil Type” on page 4.) Always check the level
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 point of
overflowing the filler neck.
Oil Sentry™
Engines are equipped with an Oil Sentry™ oil monitor.
When the oil level falls below the safe level, the engine
stops automatically. Unless you refill with oil, the
engine will not start again. See Figure 11.
