Operation 

 

22 

After you have checked and fueled the equipment and positioned it in a suitable worksite, it is 
time to start your pressure washer.  The following are the procedures necessary for safe, 
successful operation of your pressure washer. 

 

WARNING 

Carefully read and follow all instructions and safety information

 for using this pressure washer.  

Improper use or maintenance of the pressure washer can result in 

serious injury or death

 

to the 

operator or bystanders from:    

 

Carbon monoxide poisoning 

 

Fire/explosion 

 

Chemical exposure 

 

Skin/eye injury from high 
pressure spray 

 

Burns 

 

Slips/falls 

 

Electric shock 

 

Flying objects/debris 

 

 

 

Operating Instructions 

Step 1.  Connect Hoses, Water Supply, and Spray Nozzle  

Step 2.  Set Up for Chemical Spray 

(if desired)

 

Step 3.  Spraying 

Step 4.  Stopping

 

 

Each of these procedures is discussed in detail below: 
 

Step 1. Connect Hoses, Water Supply, and Spray Nozzle 

Position 
pressure 
washer for use 

Place pressure washer in a suitable location for use, 

as directed in the "Before 

Each Use, Step 3: Select Suitable Worksite" section of this manual.  A suitable 
location is:  

 

 

OUTDOORS only, away from all building air intakes. 

 

Where no flammable vapors, dusts, and gases are present. 

 

Where there is adequate, unobstructed ventilation airflow. 

 

With adequate clearance from combustible materials. 

 

On a firm, level, heat-resistant surface with good drainage and  

       nearby access to a continuous water supply. 

 

 

       DANGER:  Carbon monoxide poisoning hazard 

Exhaust fumes from both the engine and the burner contain carbon 
monoxide (CO), a poisonous gas you cannot see, smell, or taste.  The CO 
generated by the power washer can rapidly accumulate, even in areas that 
appear to be well ventilated, resulting in dangerous and fatal concentrations 
within minutes.  ONLY run pressure washer OUTDOORS and away from 
air intakes.  NEVER run pressure washer inside any enclosed or semi-
enclosed spaces, including homes, garages, basements, sheds, boxes, pick-
up truck beds, RVs, or boats.  These spaces can trap poisonous gases, 
EVEN if you run a fan or open windows.   

Fill water tank 

Ensure the water in your tank is clean.

  Debris can cause excess pump wear 

and reduce performance.
