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 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.
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.

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.
NOTE: Dispose of the old fuel/oil mix in accordance to
Federal, State and Local regulations.
