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

 

serious injury or death

 

to operator or bystanders. 

 

 WARNING – SPECIAL HAZARDS 

CO Poisoning

 

 

Exhaust from both the engine and burner contains carbon monoxide, a 
poisonous gas that can cause carbon monoxide poisoning and possible 
death if inhaled. 

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 tipover

 

 

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

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