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 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 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 washing.

CAuTION - Never use:

• Bleach, chlorine products and other corrosive

chemicals

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

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 hose 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 hose
into the detergent container.

STEp 3:

With safety latch on spray gun engaged,

secure black soap 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 flush the detergent injection
system after each use by placing the suction hose
into a bucket of clean water, then run the pressure
washer in low pressure for 1-2 minutes.
