RECOMMENDED OIL TYPE

Use a high quality oil formulated for use in 2-cycle, 
air-cooled engines.

RECOMMENDED FUEL TYPE

Always use clean, fresh, unleaded petrol (gasoline) that
is less than 60 days old.

WARNING: Petrol (gasoline) is extremely
flammable and its vapors can explode if they
are ignited. 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 away from the area.

WARNING: Remove fuel cap slowly to avoid
injury from fuel spray.

DANGER: Combustible mixture contains
petroleum distillate. Store away from heat or
open flame. Harmful or fatal if swallowed. If
swallowed, do not induce vomiting, call a
physician immediately. 
Avoid prolong contact
with skin. Wash thoroughly after handling. 

OIL AND FUEL MIXING INSTRUCTIONS

Thoroughly mix 3.8 liters of unleaded petrol (gasoline)
with 120 ml. of 2 cycle engine oil in a separate fuel can,
32:1. Do not mix them directly in the engine fuel tank.

Old and/or improperly mixed fuel are usually the main
reasons for the unit not running properly. Be sure to use
fresh, clean fuel and follow the instructions carefully for
the proper fuel/oil mixture.

NOTE:

Alcohol-blended fuel absorbs moisture (water).
As little as 1% moisture in the fuel can cause
fuel and oil to separate and form acids when
stored. If alcohol - blended fuel must be used,
use fresh fuel (less than 60 days old), and mix
according to the mixing instructions.

DEFINITION OF BLENDED FUELS

Today's fuels are often a blend of petrol (gasoline) and
one or more oxygenates such as ethanol, methanol or
MTBE (ether).

USE OF BLENDED FUELS

If you choose to use a blended fuel or its use is 
unavoidable, the following precautions are 
recommended:
1.

Always use the fresh fuel mix explained in your
operator's manual.

2.

Use the fuel additive STA-BIL® or an equivalent.

3.

Always agitate the fuel mix before fueling the unit.

4.

Drain the tank and run the engine dry before storing
the unit.

USE OF FUEL ADDITIVES

The use of fuel additive, such as STA-BIL® Fuel
Stabilizer or an equivalent, will inhibit corrosion and
minimize the formation of gum deposits. Add 23 ml. (0.8
oz.) per gallon of fuel per instructions on container.
NEVER add fuel additives directly to the unit's fuel tank.
Using a fuel additive can keep fuel fresh for up to six (6)
months.

CAUTION: For proper engine operation and
maximum reliability, pay strict attention to the
oil and fuel mixing instructions on the 
2-cycle oil container. Use a 25:1 fuel/oil ratio.
Use 2-cycle oil. Using improperly mixed fuel
can severely damage the engine.
