 PRESSURE WASHER

  

 OPERATOR’S MANUAL

  

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 the optional 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 manufac-
turer. Fill a container with pressure 
washer detergent. Place fi lter end of 
detergent suction tube into detergent 

container.

STEP 3:

 With safety latch on spray 

gun engaged, secure black detergent 
nozzle into quick coupler.  

NOTE:

  

Detergent cannot be applied using 
red, yellow, green or white nozzles.

STEP 4:

 With the engine 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 fl ush the detergent injec-
tion system after each use by placing the suction 
tube into a bucket of clean water, then run the pres-
sure washer in low pressure for 1-2 minutes.

THERMAL PUMP PROTECTION

If you run the engine on your pressure washer for 1-2 
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 de-
tergent suction tube directly into cleaning solution and 
apply to surface at low pressure (for best results, limit 
your work area to sections approximately 6 feet square 
and always apply detergent from bottom to top). Allow 
detergent to remain on surface 1-3 minutes. Do not al-
low 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 sweep-
ing motion keeping the spray nozzle approximately 
1 foot from cleaning surface. Use overlapping 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 and other corrosive 

chemicals

  •  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 fl owing by simply removing detergent 
siphon tube from bottle.
