OIL & 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
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
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.
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.

STARTING/STOPPING INSTRUCTIONS
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 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 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, pull the
starter rope with a controlled
motion until the unit starts.
Wait and allow the unit to idle
for 60 seconds.
5.
Squeeze and hold the
throttle control for an
additional 30 to 60 seconds
to allow the unit to warm up.
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 Control in the OFF (O) position until
engine comes to a complete stop (Fig. 2).
