This pressure washer produces both cold and hot water high pressure spray.  Cleaning chemicals may be 
incorporated into the spray if desired.  The pressure pump for this equipment is powered by a gasoline internal 
combustion engine and the water is heated by a kerosene/fuel-oil fired, open flame burner. 

 

WARNING 

 READ THIS MANUAL 

 

READ and UNDERSTAND this Owner's Manual and the Engine Owner's Manual completely before 
attempting to set up and use the pressure washer!  

Failure to properly set up, operate, and maintain this 

pressure washer could result in

windows, vents and air intakes, to allow proper ventilation. If you start to feel sick, 
dizzy, or weak while using the pressure washer, shut off the engine and get to fresh air 
RIGHT AWAY. 

Skin/Eye Injury

 

 

High-pressure spray can cause serious skin or eye injury, including injection injury if 
fluid pierces the skin.  Injection injury can result in blood poisoning and/or severe 
tissue damage. 

Burns

 

 

Hot spray can scald and burn skin.  

 

Hot surfaces of wand, engine and burner, as well as hot exhaust from both the engine 
and burner can cause burns. 

Slips/Falls

 

 

Spray discharge can cause puddles and slippery surfaces. 

 

Spray-gun kickback can cause operator loss of balance and falls.  

Flying Debris

 

 

High-pressure spray can cause surface damage and flying debris. 

Fire/ 
Explosion

 

 

Engine and burner sparking can ignite fuel or other flammable liquids or vapors in the 
vicinity. 

 

Hot exhaust from engine and burner can ignite combustible materials. 

Chemical 
Exposure

 

 

Cleaning chemical vapors or contact with skin may be hazardous. 

Electric shock

 

 

Spray contact with electrical sources can cause electric shock. 

Trailer 
tip over

 

 

Sudden stopping or turning while towing the pressure washer with a filled water tank 
can result in driving instability and/or trailer tip over. 

A summary of important safety information is provided at the end of the manual.
