NOTE:
Be sure to read these instructions carefully
before attempting to start or operate this
equipment. Using old or improper oil or fuel
can cause engine damage.

Any attempt to crank or start the engine
before it has been properly serviced with the

ReCoMMended oil Type
Using the proper type and weight of oil in the crank-
case is extremely important. Check the oil before
each use and change the oil regularly. Failure to use
the correct oil, or using dirty oil, can cause prema-

service classification SJ or higher (example: SL or
SM). Do NOT use oil designated for diesel engines
only (example: CD).
The recommended oil weights include the following:
• During summer months: SAE 30. An acceptable
substitute is SAE 10W-30.
• During winter months: SAE 5W-30 or synthetic
5W-30. DO NOT USE SAE 10W-40.
• The use of synthetic oil is acceptable after the first
oil change.
The crankcase oil capacities are listed in the table
below. Use no special additives. Make sure that the unit
is level when filling with oil. DO NOT OVERFILL.
