OIL AND 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.
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. 4).
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. 4).
2. Tip unit so that the back of the engine is facing up in a vertical position.
3. Remove the oil fill plug from the crankcase (Fig. 6).
4. Pour the entire bottle of oil into the oil fill hole (Fig. 5).

RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper unit performance. Be
sure to use fresh, clean, unleaded gasoline.
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
Primer Bulb
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
Using Fuel Additives
WARNING:
immediately. Avoid creating a source of ignition for spilt fuel. Do not start the engine until
fuel vapors dissipate.
WARNING:
the engine and allow it to cool before filling the fuel tank. Do not smoke while filling the
tank. Keep sparks and open flames at a distance from the area.
The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent, will inhibit corrosion and
minimize the formation of gum deposits. Using a fuel additive can keep fuel from forming harmful deposits
in the carburetor for up to six (6) months. Add 0.8 oz. (23 ml.) of fuel additive per gallon of fuel according
to the instructions on the container. NEVER add fuel additives directly to the unit's gas tank.
