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.

Remove fuel cap slowly to avoid

injury from fuel spray. Never operate the unit
without the fuel cap securely in place.

Add fuel in a clean, well-

ventilated outdoor area. Wipe up any spilled
fuel immediately. Avoid creating a source of
ignition for spilled fuel. Do not start the
engine until fuel vapors dissipate.

NOTE: Dispose of the old petrol/oil mix in accordance

Old and/or improperly mixed fuel is the main reason for
improper unit performance. Be sure to use fresh, clean
unleaded petrol. Follow the instructions carefully for the
proper petrol/oil mixture.

Today's fuels are often a blend of fuel 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).

If you choose to use a blended petrol, or its use is
unavoidable, follow recommended precautions:

• Always use fresh fuel mix per 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

The bottle of 2-cycle oil that came with your unit
contains a petrol additive which will help inhibit
corrosion and minimize the formation of gum deposits.
It is recommended that you use only 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. 

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.

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 fuel
tank. See the table below for specific petrol and oil mixing
ratios.
