SAFETY AND GENERAL INFORMATION
OIL RECOMMENDATIONS
Using the proper type and weight of oil in the engine
crankcase and in the gear reduction unit is extremely
important, as is checking oil daily and changing oil
regularly. Failure to use the correct oil or using dirty oil
causes premature engine wear and failure.
Oil Type
Use high-quality detergent oil of API (American
Petroleum Institute) Service Class SF or SG. Select the
viscosity based on the air temperature at the time of
operation as shown in the table.

Straight 30-weight oil is preferred.
SAE 10W-30 and
10W-40 are not recommended above 32°F (0°C).
Using these oils substantially increases oil consump-
tion and combustion chamber deposits.
NOTE:
Using other than Service Class SF or SG oil or
extending oil change intervals longer than rec-
ommended could cause engine damage
which is not covered by the engine warranty.
A logo or symbol on oil containers identifies the
API service class and SAE viscosity grade.
Rod
Check Oil Level
Check oil level BEFORE EACH USE.
NOTE: Do not operate the engine with the oil level
below "2 mark or over "F" mark on
dipstick.
Operating
Range
Change Oil
For a new engine, change oil after the first 5 hours of
operation. Thereafter, change the oil as specified in
the following "Oil Change Intervals" table.
For an overhauled engine or those rebuilt with a
new short block, use straight 30-weight Service
Class SF or SG oil for the first 5 hours of operation.
Change the oil after this initial run-in period. Refill
with Service Class SF or SG oil as specified in the
table.
