OIL AND FUEL INFORMATION

RECOMMENDED OIL TYPE
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.
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.
4-CYCLE OIL USE
NOTE: This unit is shipped without oil. In order to avoid damage to the unit, put oil in the crankcase before
attempting to start the unit.
The unit is supplied with one 3.04 fluid oz. (90 ml) bottle of SAE 30 SF, SG, SH oil.
NOTE: Save the bottle of oil. It can be used to measure the correct amount during future oil changes. See Changing
the Oil.
NOTE: Never add oil to the fuel or fuel tank.
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
WARNING:
It has been proven that fuel containing greater than 10% ethanol will likely damage this engine
and void the warranty.
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 choosing 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
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.
WARNING:
Gasoline is extremely flammable. Ignited vapors may explode. Always stop 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.
WARNING:
Remove fuel cap slowly to avoid injury from fuel spray. Never operate the unit without the
fuel cap securely in place.
WARNING:
Add fuel in a clean, level and well ventilated outdoor area. Wipe up any spilled fuel immediately.
Avoid creating a source of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate.
