OIL AND FUEL MIXING INSTRUCTIONS
Be sure to use fresh, clean unleaded fuel and follow instructions carefully for proper fuel/oil mixture.
Defi nition of Blended Fuels
Today’s fuels are often a blend of gasoline and oxygenates such as ethanol, methanol, or MTBE (ether)
which absorb water. Use fuel within 30 days of purchase. Blended fuels older than 30 days will affect
the performance and life of the engine.
Using Blended Fuels
If the use of blended fuel is unavoidable, follow recommended precautions:
•
Always use the fresh fuel mix explained in the operator’s manual
•
Always agitate the fuel mix before fueling the unit
•
Drain the tank and run the engine dry before storing the unit
Using Fuel Additives
It is recommended to use the manufacturers 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.
Mixing The Fuel
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded fuel in a separate fuel can. Use a
40:1 fuel/oil ratio. Do not mix them directly in the engine fuel tank.
IF.
..
the unit came with a bottle of 2-cycle oil; pour the entire bottle into 1 gallon of gas and mix
thoroughly.
NOTE:
One gallon (3.8 liters) of unleaded fuel mixed with one 3.2 oz. (95 ml.) bottle of 2-cycle oil
makes a 40:1 fuel/oil ratio.
NOTE:
Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations.
OIL AND FUEL
WARNING:
Fuel containing greater than 10% ethanol will likely damage the engine and
void the warranty.
WARNING:
Gasoline is extremely fl ammable. Ignited vapors may explode. Always stop
the engine and allow it to cool before fi lling the fuel tank. Do not smoke while fi lling the
tank. Keep sparks and open fl ames 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.
MAINTENANCE SCHEDULE
Perform these required maintenance procedures at the frequency stated in the table. These
procedures should also be a part of any seasonal tune-up.

An authorized service dealer should make carburetor
adjustments.
If, after checking the fuel and cleaning the air fi lter, the engine still
will not idle, adjust the idle speed screw as follows:
1. Start the engine and let it run at a high idle for a minute to
warm up. Refer to Starting/Stopping Instructions.
2. Move the cruise control to the SLOW position and let
the engine idle. If the engine stops, insert a small Phillips
screwdriver in between the air fi lter cover and the engine
cover (Fig. 7). Turn the idle speed screw in, clockwise, 1/8 of a
