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.

WARNING:

Remove the fuel cap slowly to avoid injury from fuel spray. Never operate the unit without

the fuel cap securely in place.

CAUTION:

For proper engine operation and maximum reliability, pay strict attention to the oil and fuel

mixing instructions on the 2-cycle oil container. Using improperly mixed fuel can severely damage the engine.

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.
