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:
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.
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 fuel
additive container. NEVER add fuel additives directly to the unit's gas tank.
