OIL AND PETROL INFORMATION
NOTE: Dispose of the old petrol/oil mix in accordance to
Federal, State and Local regulations.
OIL AND PETROL 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 petrol. Follow the instructions carefully
for the proper petrol/oil mixture.
Definition of Blended Petrols
Today's petrols are often a blend of petrol and
oxygenates such as ethanol, methanol, or MTBE (ether).
Alcohol-blended petrol absorbs water. As little as 1%
water in the petrol can make petrol and oil separate. It
forms acids when stored. When using alcohol-blended
petrol, use fresh petrol (less than 60 days old).
Using Blended Petrols
If you choose to use a blended petrol, 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
® Petrol Stabilizer or an equivalent. Add 23 ml
(0.8 oz) 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 petrol in a separate fuel can. Use a 40:1
petrol/oil ratio. Do not mix them directly in the engine
fuel tank. See the table below for specific petrol and oil
mixing ratios.
NOTE: 3.8 liters (1 gallon) of unleaded petrol mixed with
one 95 ml (3.2 oz) bottle of 2-cycle oil makes a
40:1 petrol/oil ratio.

MIXING RATIO - 40:1
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:
Petrol 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:
For proper engine
operation and
maximum reliability, pay strict attention to
the oil and petrol mixing instructions on the
2-cycle oil container. Using improperly mixed
fuel can severely damage the engine.
CAUTION:
