THERMAL PUMP PROTECTION

If you run the motor on your pressure washer for 3-5 
minutes without pressing the trigger on the spray gun, 
circulating water in the pump can reach high tempera-
tures. When the water reaches this temperature, the 
pump protector engages and cools the pump by dis-
charging the warm water onto the ground. This thermal 
device prevents internal damage to the pump.

CLEANINg TIPS

Pre-rinse cleaning surface with fresh water. Place deter-
gent suction tube directly into cleaning solution and apply 
to surface at low pressure (for best results, limit your work 
area  to  sections  approximately  6'  square  and  always 
apply detergent from bottom to top). Allow detergent to 
remain on surface 1-3 minutes. Do not allow detergent 
to dry on surface. If surface appears to be drying, simply 
wet down surface with fresh water. If needed, use brush 
to remove stubborn dirt. Rinse at high pressure from top 
to bottom in an even sweeping motion keeping the spray 
nozzle approximately 1' from cleaning surface. Use over-
lapping strokes as you clean and rinse any surface. For 
best surface cleaning action spray at a slight angle.

Recommendations:

  •  Before  cleaning  any  surface,  an  inconspicuous 

area should be cleaned to test spray pattern and 

distance for maximum cleaning results.

  •   If  painted  surfaces  are  peeling  or  chipping,  use 

extreme caution as pressure washer may remove 

the loose paint from the surface.

  •   Keep the spray nozzle a safe distance from the  

surface you plan to clean. High pressure wash a 

small area, then check the surface for damage. If 

no damage is found, continue to pressure wash-
ing.

       CAUTION - Never use:
  •   Bleach, chlorine products or other corrosive chemi-

cals

  •   Liquids  containing  solvents  (i.e.,  paint  thinner, 

gasoline, oils)

  •   Tri-sodium phosphate products
  •   Ammonia products
  •   Acid-based products
These chemicals will harm the machine and will dam-
age the surface being cleaned.

RINSINg

It will take a few seconds for the detergent to clear.  
Apply safety latch to spray gun. Remove  black soap 
nozzle from the quick coupler. Select and install the 
desired high pressure nozzle. 

NOTE: 

You can also stop 

detergent from flowing by simply removing detergent 
siphon tube from bottle.

WARNING:  Some  detergents 
may  be  harmful  if  inhaled  or 
ingested,  causing  severe  nau-
sea, fainting or poisoning. The 
harmful  elements  may  cause 
property  damage  or  severe 
injury.

STEP 1: 

Connect detergent injector to discharge nipple 

on machine. Connect high pressure hose to injector 
with quick coupler. (Check to make sure locking coupler 
sleeves are in proper position before applying water 
pressure).

STEP  2:

  Use  detergent  designed 

specifically  for  pressure  washers. 
Household detergents could dam-
age  the  pump.  Prepare  detergent 
solution as required by the manu-
facturer.  Fill a container with pres-
sure  washer  detergent.  Place  the 
filter end of detergent suction tube 
into the detergent container.

STEP 3:

 With safety latch on spray 

gun  engaged,  secure  black  de-
tergent  nozzle  into  quick  coupler.  

NOTE:

  Detergent cannot be applied 

using a pressure nozzle.

STEP 4:

 With the motor running, pull trigger to operate 

machine. Liquid detergent is drawn into the machine 
and mixed with water. Apply detergent to work area. 
Do not allow detergent to dry on surface. 

IMPORTANT: You must flush the detergent injection 
system after each use by placing the suction tube 
into a bucket of clean water, then run the pressure 
washer in low pressure for 1-2 minutes.
