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, 
lightweight 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.
