WARNING: Some detergents 
may be harmful if inhaled or in-
gested, causing severe nausea, 
fainting or poisoning. The harm-
ful elements may cause property 
damage or severe injury.

STEP 1:

 Use detergent designed 

specifi cally 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 
fi lter end of detergent suction tube 
into the detergent container.

STEP 2:

 Open detergent valve to desired mixture ratio 

by turning detergent knob.

STEP 3:

 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 line after each use by placing the suction 
tube into a bucket of clean water, then run the pres-
sure washer for 1-2 minutes.

THERMAL PUMP PROTECTION

If you run the engine 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 de-
tergent suction tube directly into cleaning solution and 
apply to surface (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 allow deter-
gent 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 from top to 
bottom in an even sweeping 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. Open detergent valve. 
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.
