FUEL SAFETY WARNINGS

WARNING: Gasoline is highly flammable, and its

vapors can explode if ignited. Take the following precautions:

Store fuel only in containers specifically designed and approved for the storage of such material.

Avoid creating a source of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate.

Always stop the engine and allow it to cool before filling the fuel tank. Never remove the cap of the fuel tank, or add fuel, when the engine is hot. Never operate the unit without the fuel cap securely in place. Loosen the fuel tank cap slowly to relieve any pressure in the tank.

Add fuel in a clean, well-ventilated outdoor area where there are no sparks or flames. Slowly remove the fuel cap only after stopping engine. Do not smoke while fueling or mixing fuel. Wipe up any spilled fuel from the unit immediately. Always wipe unit dry before using.

Move the unit at least 30 feet (9.1 m) from the fueling source and site before starting the engine. Do not smoke. Keep sparks and open flames away from the area while adding fuel or operating the unit.
