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
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
®
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
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.

STARTING INSTRUCTIONS
STARTING/STOPPING INSTRUCTIONS
1. Mix gas with oil. See
Oil and Fuel Mixing
Instructions.
2. Fill the fuel tank with
the fuel/oil mixture.
NOTE: There is no need
to turn the unit
on. The On/Off
Stop Control is in
the ON ( I )
position at all
times (Fig. 2).
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. 3). If you can’t
see fuel in the bulb,
press and release the
bulb as many times as it
takes until you can see
fuel in it.
4.
Crouch in the starting
position (Fig. 4). Do not
squeeze the throttle,
and pull the starter rope
with a controlled and
steady motion until the
unit starts. Wait 10 to
15 seconds, then
squeeze the throttle to
control the cutting
speed.
NOTE:
The unit uses the
INCREDI-PULL™ 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.
IF... The engine does not start, go back to step 3.
NOTE: 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).

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.
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. 5).
To avoid serious injury, the operator and unit must be
in a stable position while starting.
