Old and/or improperly mixed f uel a re themain reasons fortheunit n ot
running properly. Besure touse fresh, clean u nleaded fuel. F ollow t he
instructions carefully forthe proper fuel/oil mixture.
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. It forms acids when stored. When using alcohol-blended
fuel, use fresh fuel (less than 60 days old).
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable, follow
recommended precautions:
• Always use the fresh fuel mix explained in your 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
The bottle of 2-cycle oil that came with your unit contains a fuel
additive which will help inhibit corrosion and minimize the formation of
gum deposits. It is recommended that you use our 2-cycle oil with this
unit. If unavailable, use a good 2-cycle oil de-signed for air-cooled
engines along with a fuel additive, such as STA-BIL_"> G as 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.
I _ _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.
Thoroughly mix the proper ratio of 2-cycle engine oil with unleaded
gasoline in a separate fuel can. Use a 40:1 fuel/oil ratio. Do not mix
them directly in the engine fuel tank. See the table below for
specific gas and oil mixing
ratios.
NOTE: One gallon (3.8 liters)
of unleaded gasoline
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.

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, well ventilated outdoor area. Wipe up any spilled fuel immediately. Avoid creating
a source of ignition for spilt fuel. Do not start the engine
until fuel vapors dissipate.
WARNING:
Operate this unit only 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. 4).
To avoid serious injury, the operator and unit must be
in a stable position while starting.
STARTING INSTRUCTIONS
1. Mix gas with oil. See Stop/Off (O} ___,_,_
Oil and Fuel Mixing /_-_Y'/OL_
Instructions.
2. Fill the fuel tank with
the fuel/oil mixture.

Fully pressand release
the primer bulb 10 times
slowly. Some amount of
fuel should be visiblein
the primer bulb and fuel
lines(Fig.3). Ifyou can't
see fuel in the bulb,
pressand releasethe
bulb as many times as it
takes until you can see
fuel in it.
Crouch in the starting
position (Fig. 4). Do not

pull the starter rope with
a controlled and steady
motion until the unit
starts. Wait 30 to 60
seconds, then squeeze
the throttle to control
the cutting speed. For
temperatures below
50° F ( 10°C), please
refer to the note below.

For temperatures below 50° F ( 10° C), allow the unit to idle for
the full 60 seconds before squeezing the throttle. Then
squeeze the throttle and hold at full throttle for an additional
60 seconds before allowing the unit to return to idle.
The unit uses the INCREDI=PULL
TM
starting system, which
significantly reduces the effort required to start the engine.
You must pull the starter rope out far enough to hear the
engine attempt to start. There is no need to pull the rope
briskly-- there is no harsh resistance when pulling. Be aware
that this starting method is vastly different from (and much
easier than) what you may be used to.
The engine does not start, go back to step 3.
If the unit is hot and fails to start within 3 pulls of the
starter rope, squeeze the throttle control and pull the
starter rope until the unit starts.
STOPPING INSTRUCTIONS
1. Release your hand from the throttle control. Allow the
engine to cool down by idling.
2. Press and hold On/Off Stop Control in the OFF (O) position
until engine comes to a complete stop (Fig. 2).
