Use oil viscosity based on the expected air temperature
range during the period between oil changes.
Use a high quality detergent oil with API classifications of
SJ or higher.
Check oil level before each operation and ensure that it
is maintained.
CAUTION: THIS ENGINE CRANKCASE IS NOT
FILLED WITH OIL AT THE FACTORY, SO BE
SURE TO FILL IT BEFORE OPERATING THE
ENGINE.
ENGINE OIL CAPACITY
NOTE: These engines are equipped with a “Low Oil”
shut-off system for engine protection. If the
engine fails to start, check engine crankcase
for oil.
To fill with oil:
1. Level the engine to ensure accurate inspection and
to prevent overfilling.
2. Unscrew the oil gauge (Fig. 1), wipe the dipstick dry.
Reinsert the oil gauge back into the oil fill gauge opening.
Remove the oil gauge and check the oil level.
3. The oil level should be between the full and low marks
on the dipstick. (Fig. 2)
NOTE: When checking the oil be sure the engine is
level.
4. Fill with oil as required through the oil fill gauge
opening.
5. Replace the oil gauge and screw in firmly.
