2. The black, low pressure chemical nozzle must be 

used to spray chemicals. 

3. Squeeze the spray gun trigger.  The chemical injector 

will draw the chemical into the water stream. 

4. Spray detergent onto the surface and allow it to soak.  

Chemicals need time to work properly.  Follow the 
chemical manufacturer’s recommendations for the 
recommended time. 

5. Change back to high pressure to rinse by inserting 

one of the high pressure nozzles. 

6. Hold the lance with two hands in a sturdy stance 

position. 

7. Point lance at dirty surface and squeeze trigger.

 

8. Wash from the bottom to the top, using side to side 

motions.  This washes away heavy dirt and allows the 
detergent to soak as you work toward the top. 

9. Use the width of the spray pattern to wash in a wide 

path.  Overlap spray paths for complete coverage. 

10.The nozzle should be 12” to 24” from the work, closer 

for tough areas.   

 

Caution: Be careful on painted or delicate surfaces, 
the pressure may damage the surface if the nozzle is 
too close. 
 

11. Small parts should be washed in a basket so the 

pressure does not push them away.  Larger, light 
weight parts should be clamped down. 

12. The pressure washer is set to the maximum rated 

pressure when it leaves the factory.  To adjust the 
pressure, turn the unloader knob counter-clockwise. 

 
 
 
 
 
 
 

 
 
 
 
 

WARNING:  Do not alter the unloader valve’s 
maximum pressure. Excess pressures could cause 
serious injury and/or pump damage.  Any alteration 
other than turning the adjustment knob will void 
your warranty. 
 
For Steam (Optional) 

1. Set the thermostat to 250

°

F. 

2. Turn the Heat switch ON. 
3. Insert the steam nozzle into the nozzle holder. 

 
To Stop 

1. If detergents were used, draw clear water through the 

detergent inlet line to purge detergent. Failure to do 
so may clog the chemical injector. 

2. If the burner was used, turn off the “Heat” switch and 

pump cold water through the coil for 3 minutes.  
Insufficient cool down period of high pressure hose 
will cause excessive wear and eventual rupturing of 
hose. 

3. Turn the pump switch OFF. 
4. Turn OFF the water supply. 
5. Squeeze the trigger to relieve the system pressure.
