Always inspect (engine and burner) fuel systems & check for leaks BEFORE starting pressure washer. Do not start pressure washer until all needed repairs have been completed.

WARNING: Fuel leak hazard

Gasoline and burner fuels are highly explosive and fuel leaks can result in fire or explosions. You can be burned and seriously injured if the fuel system is not properly hooked up or there is a fuel leak when you start the engine.

Inspect the entire fuel system. Look for:

• signs of leaks or deterioration,

• chafed or spongy fuel hose,

• loose connections,

• loose or missing fuel hose clamps,

• damaged gasoline tank, or

• defective gasoline shut-off valve.

WARNING: Fuel fire/explosion hazard

Gasoline is highly flammable and explosive. Burner fuels are combustible at warm temperatures. Heat, sparks, and flames can ignite fuel vapors, which can become widespread during fueling. A flash fire and/or explosion could result and cause serious injury or death. Always use extreme care when handling fuels. Carefully follow all instructions to avoid the following conditions which could result in fuel ignition:

• gas vapor collection inside enclosures

• static electric sparks

• sparks from electric wiring, batteries, or running engines

• sources of heat (such as a hot engine, burner or exhaust)

• open flames, including pilot lights
