OIL & FUEL INFORMATION
WARNING:
OVERFILLING OIL CRANKCASE MAY
CAUSE SERIOUS PERSONAL INJURY. Check and maintain
the proper oil level in the crank case; it is important and
cannot be overemphasized. Check the oil before each use
and change it as needed. See Changing the Oil.
RECOMMENDED OIL TYPE
Using the proper type and weight of oil in the crankcase 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 premature
engine wear and failure.
Use a high-quality SAE 30 weight oil of API (American Petroleum Institute)
service class SF, SG, SH.

OIL & FUEL INFORMATION
ADDING OIL TO CRANKCASE: INITIAL USE
NOTE: This unit is shipped without oil. In order to avoid damage to
the unit, put oil in the crankcase before you attempt to start
the unit.
Your unit is supplied with one 3.04 fluid oz. (90 ml.) bottle of SAE 30
SF, SG, SH oil (Fig. 6).
NOTE: Save the bottle of oil.
It can be used to
measure the correct
amount during future
oil changes. See
Changing the Oil.
1. Unscrew the top of the
bottle of oil and remove
the paper seal covering
the opening. Replace the
top. Next, cut the tip off
the funnel spout (Fig. 6).
2. Place unit on a flat, level
surface.
3. Remove the oil fill plug from
the crankcase (Fig. 8).
4. Pour the entire bottle of oil
into the oil fill hole (Fig. 7).
NOTE: Never add oil to the
fuel or fuel tank.
5. Wipe up any oil that may
have spilled and reinstall
the oil fill plug.
Check oil before each use and
change as needed. Refer to
Checking the Oil Level.
RECOMMENDED FUEL
TYPE
Old fuel is the primary reason
for improper unit performance.
Be sure to use fresh, clean,
unleaded gasoline.
NOTE: Dispose of the old
gasoline in accordance to Federal, State and Local
regulations.
NOTE: This is a four cycle engine. In order to avoid damage to the
unit, do not mix oil with gasoline.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates such as
ethanol, methanol or MTBE (ether). Alcohol-blended fuel absorbs
water. As little as 1% water in the fuel can make fuel and oil separate
or form acids when stored. Use fresh fuel (less than 60 days old),
when using alcohol-blended fuel.
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable, follow
recommended precautions:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL® or an equivalent
• Drain tank and run the engine dry before storing unit
