OIL & PETROL INFORMATION
OIL AND
FUEL MIXING
INSTRUCTIONS
Old and/or improperly
mixed fuel are the main reasons for
improper
unit performance.
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 petrol 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 opera-
tor'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 petrol additive, such as STA-BIL_ Petrol
Stabilizer or an equivalent.
Add 23 ml (0.8 oz) of petrol
additive
per gallon of petrol according
to the instructions on
the container. NEVER add petrol additives
directly to the
unit's petrol tank.
CAUTION: For proper engine operation
and max-
imum reliability,
pay strict attention
to the oil and
petrol mixing instructions
on the 2-cycle oil con-
tainer. Using improperly
mixed petrol can severe-
ly damage the engine.
Thoroughly
mix the proper ratio of 2-cycle engine oil with
unleaded
petrol in a separate petrol can. Use a 40:1 petrol/oil
ratio. Do not mix them directly
in the engine petrol 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.

WARNING: Petrol is extremely flammable.
Ignited
Vapors may explode. Always stop the engine and
allow it to cool before filling the petrol tank. Do not
smoke while filling the tank. Keep sparks and open
flames at a distance from the area.
WARNING:
Remove petrol
cap slowly to avoid
injury from petrol spray. Never operate the unit
without the petrol cap securely in place.
NOTE:
WARNING: Add petrol in a clean, well ventilated
area outdoors.
Wipe up any spilled petrol imme-
diately.
Avoid creating
a source of ignition
for
spilt petrol.
Do not start the engine until petrol
vapors dissipate.
Dispose of the old petrol/oil
mix in accordance
to Federal, State and Local regulations.
