Detergents And General Operating 
Techniques

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

AVERTISSEMENT: Certains 
détergents peuvent être dangereux 
s'ils sont inhalés ou ingérés, 

provoquant de fortes nausées, des 
évanouissements et l'empoisonnement. Les 
éléments dangereux peuvent causer des 
dommages à la propriété ou des blessures graves

STEP 1:

 Use detergent designed 

specifically for pressure washers. 
Household detergents could damage 
the pump. Prepare detergent solution 
as required by the manufacturer. Fill 
a container with pressure washer 
detergent. Place the filter end of 
detergent suction tube into the 
detergent container.

STEP 2:

 Apply safety latch to 

spray gun trigger. Secure black 
detergent nozzle into quick 
coupler. 

NOTE:

 Detergent 

cannot be applied using the 
Yellow nozzle.

STEP 3:

 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.

Thermal Pump Protection

If you run your pressure washer for 2 minutes without 
pressing the trigger on the spray gun, circulating water in 
the pump can reach high temperatures. When the water 
reaches this temperature, the pump protector engages 
and cools the pump by discharging 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 
detergent 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 
washing.

      

 CAUTION - Never use:

Bleach, chlorine or 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 damage 
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.
