OIL AND FUEL INFORMATION

OIL AND FUEL MIXING INSTRUCTIONS
Old and/or improperly mixed fuel are the main reasons for the unit not running properly. Be sure to use
fresh, clean unleaded fuel. Follow the instructions carefully for the proper fuel/oil mixture.
DEFINITION OF BLENDED FUELS
WARNING:
DO NOT USE E85 FUEL IN THIS UNIT. 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. It
forms acids when stored. When using alcohol-blended fuel, use fresh fuel (less than 30 days old).
USING BLENDED FUELS
If choosing to use a blended fuel, or its use is unavoidable, follow recommended precautions:
• Always use the fresh fuel mix explained in the operator's manual
• Use the fuel additive STA-BIL® or an equivalent
• Drain the tank and run the engine dry before storing the unit
USING FUEL ADDITIVES
CAUTION: For proper engine operation and maximum reliability, pay strict attention to
the oil and fuel mixing instructions on the 2-cycle oil container. Using improperly mixed fuel
can severely damage the engine.
The bottle of 2-cycle oil contains a fuel additive which will help inhibit
corrosion and minimize the formation of gum deposits. It is
recommended to use our 2-cycle oil with this unit.
If unavailable, use a good 2-cycle oil designed for air-cooled engines
along with a fuel additive, such as STA-BIL Gas Stabilizer or an
equivalent. 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 fuel tank.
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded
fuel in a separate fuel can. Use a 50:1 fuel/oil ratio. Do not mix them
directly in the engine fuel tank. See the table for specific gas and oil
mixing ratios.
NOTE: One gallon (3.8 liters) of unleaded fuel mixed with one 2.6 oz. (77 ml) bottle of 2-cycle oil makes a 50:1
fuel/oil ratio.
NOTE: Dispose of the old fuel/oil mix in accordance with federal, state and local regulations.
FUELING THE UNIT
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.
1. Remove the fuel cap.
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.
2. Place the gas container's spout into the fill hole on the fuel tank and fill the tank.
NOTE: Do not overfill the tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the fueling source and site before starting the engine.

STARTING/STOPPING INSTRUCTIONS

WARNING:
Operate this unit in a well-ventilated outdoor area. Carbon monoxide
exhaust fumes can be lethal in a confined area.
WARNING:
Avoid accidental starting. Make sure you are in the starting position when
pulling the starter rope (Fig. 22). To avoid serious injury, the operator and unit must be
in a stable position while starting.
STARTING INSTRUCTIONS
1. Mix fuel with oil. See Oil and Fuel Mixing Instructions.
2. Fill the fuel tank with fresh, clean fuel mix. Refer to Fueling the Unit.
NOTE: There is no need to turn the unit on. The On/Off Control is in the
ON ( I ) position at all times (Fig. 20).
3. Fully press and release the primer bulb 10 times, slowly. Some amount
of fuel should be visible in the primer bulb and fuel lines (Fig. 21). If fuel
can not be seen in the bulb, press and release the bulb until fuel is
visible.
4. Place the choke lever in Position 1 (Fig. 21).
5. Crouch in the starting position (Fig. 22). Press the throttle lock-out in
and squeeze the throttle control lever. Pull the starter rope 5 times.
6. Place the choke lever in Position 2 (Fig. 21)
7. Press the throttle lock-out in and squeeze the throttle control. Pull the
starter rope in a controlled motion 3 to 5 times to start engine.
8. Keep the throttle squeezed and allow the engine to warm up for 30 to
60 seconds.
9. Continue squeezing the throttle control, move the choke lever to Position
3 (Fig. 21) and continue warming the engine for an additional 60 seconds.
