Be sure to use fresh, clean, unleaded gasoline.

the unit, do not mix oil with gasoline.
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 or form acids when stored. Use fresh fuel
(less than 60 days old), when using alcohol-blended fuel.
Using Blended Fuels
If you choose to use a blended fuel, or its use is unavoidable,
follow recommended precautions:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL® or an equivalent
• Drain tank and run the engine dry before storing unit
Using Fuel Additives
l_ WARNING: Add fuel in a clean, well ventilated
outdoor area. Wipe up any spilled fuel immediately.
M Avoid creating a source of ignition for spilt fuel. Do
not start the engine until fuel vapors dissipate.
,_m _ WARNING: Gasoline 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.
The use of fuel additives, such as STA-BIL® Gas Stabilizer or
an equivalent, will inhibit corrosion and minimize the formation
of gum deposits. Using a fuel additive can keep fuel from
forming harmful deposits in the carburetor for up to six (6)
months. 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 gas tank.
FUELING THE UNIT
WARNING: Remove fuel cap slowly to avoid injury I
from fuel spray. Never operate the unit without the
I
fuel cap securely in place.
1. Remove the fuel cap (Fig. 5).
2. Place the gas container's spout into the fill hole on the fuel
tank (Fig. 5) and fill the tank.
NOTE: Do not overfill the tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
