Applying Detergent & 
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 déter-
gents peuvent être dangereux s'ils 
sont inhalés ou ingérés, provoquant 

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

STEP 1: 

Use detergent designed specif-

ically 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:

 Open detergent valve counter-

clockwise until you obtain desired mixture. Detergent will 
mix with the high pressure water stream.

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 from your 
pressure washer after each use by placing the suction 
tube into a bucket of clean water, then run the 
pressure washer for 2 minutes.

NOTE:  If you remove detergent siphon tube from 
container or allow container to empty, it will cause low 
pressure by sucking air, which will damage the pump

.

Thermal Pump Protection

If you run the engine for 3-5 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. 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 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 foot from cleaning surface. Use overlap-
ping 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 products and other corrosive 
chemicals

Liquids containing solvents (i.e., paint thinner, 
gasoline, oils)

Tri-sodium phosphate products

Ammonia products or acid-based products

ATTENTION: Ne jamais utiliser :

Eau de Javel, produits à base de chlore et autres 
produits chimiques corrosifs

Liquides contenant des solvants (c.-à-d. diluant à 
peinture, essence, huiles, etc.)

Produits à base de tripolyphosphate de sodium

Ammoniac ou produits à base d'acide

These chemicals will harm the machine and will damage 
the surface being cleaned.

Rinsing

Turn detergent valve clockwise to close. Operate pressure 
washer and allow a few seconds for the detergent to clear.
