CAUTION: The use of non-synthetic multi-
viscosity oils (5W-30, 10W-30, etc.) in
temperatures above 40°F (4°C) will result in
higher than normal oil consumption. When using
a multi-viscosity oil, check oil level more
frequently. SAE 30 oil, if used below 40°F (4°C),
will result in hard starting and possible engine
bore damage due to inadequate lubrication.
NOTE: The use of synthetic oils does not alter
the oil change intervals.
Changing Oil
Change oil and filter (if equipped) after the first 5-
8 hours. Thereafter, change oil every 100 hours
of operation.
Change oil more often if engine is operated in
dirty or dusty conditions or if engine is operated
under heavy loads and/or in high ambient air
temperatures.

5. Screw filter on by hand until gasket
contacts oil filter mounting adapter. Then
tighten an additional 1/2 to 3/4 turn.
6. Clean area around oil fill cap and tube ([B]
Fig. 2).
7. Fill with the correct amount of new oil.
SEE SECTION 14- ENGINE SPECIFICATIONS.
Start engine and run at idle for a minute or so.
8. Shut engine off and wait for oil to settle
back into the cylinder.
9. Check dipstick. If necessary, add more oil
slowly to bring oil level to FULL mark ([A]
Fig. 4) on dipstick.

CAUTION: Do not overfill. Overfilling can cause
seals to fail or overheating due to oil foaming.
10. Replace oil fill cap and dipstick.
11. Start and run engine. Check for oil leaks.
