customized for pressure washer use 
on specific cleaning tasks.  These 
detergents are approximately as 
thick as water.  The use of thicker 
detergents, such as dish soap, will 
clog the chemical injection system 
and prevent the application of the 
detergent.

The cleaning power of detergents 
comes from applying them to a 
surface and giving the chemicals 
time to break down the dirt and 
grime.  Detergents work best when 
applied at low pressure.

The combination of chemical action 
and high pressure rinsing is very 
effective.  On vertical surfaces, 
apply the detergent starting at 
the bottom and working your way 
upward.  This will prevent the 
detergent from sliding down and 
causing streaks.

High pressure rinsing should also 
progress from the bottom to top.  
On particularly tough stains, it 
may be necessary to use a brush in 
combination with detergents and 
high pressure rinsing.

1.  The lance is affected by 

pressure during operation; 
therefore hold it firmly with 
both hands and point the 
nozzle toward the ground.

2.  Activate by pulling the trigger 

of the gun/spray handle.

3.  Adjust the distance to the 

cleaning surface, which will 
also adjust your pressure of the 
nozzle.

4.  Spray pattern shape and 

intensity can be changed by 
twisting the spray adjuster at 
the end of the lance.  Keep 
hands clear of the front of the 
lance to prevent injury.  

1.  Press the ON/OFF switch to 

“OFF” on the pressure washer.

2.  Disconnect the plug from the 

power source.

3.  Shut off the water supply.
4.  Activate the spray handle to 

relieve the machine of pressure.

5.  Lock the trigger into the “OFF” 

position.
