SAFETY WARNING WARNING Starting engine creates sparking. Gasoline and its vapors are extremely flammable and explosive. Sparking can ignite nearby flammable gases. Fire or explosion can cause severe burns or death. Explosion and fire could result. WHEN ADDING FUEL • If there is natural or LP gas leakage in area, do not start engine. • Do not use pressurized starting fluids because vapors are flammable. • Turn engine OFF and let engine cool at least 2 minutes before removing gas cap.
