ASSEMBLY

•  Connecting water hose to inlet first,and turn on the 
tap . Make sure the machine is full of water .  .Then turn 
on the main switch .The most important thing is not for-
get to press the   in electronic control center to start 
the machine .
•  The electronic control center has three pressure 
modes for users to choose . There are soft, medium and 
strong mode .The pressure depends upon which attach-
ment is best suited to the surface you are cleaning .  
•  If you want to increase the pressure level, press the + 
button in the electronic control center .
•  If you want to reduce the pressure level, press the - 
button in the electronic control center .
•  When you increase the pressure level to make the 
pressure indicator turn red, it means that the machine is 
working at the maximum pressure . At this time, please 
do not let the machine work continuously for more than 
15 minutes under the maximum pressure . See picture 5 .

PRE-OPERATION:

Adjusting fan pattern

The angle of spray coming out of the lance may be ad-
justed on some lances by rotating the nozzle . This will 
vary the spray pattern from approximately a 0° narrow 
high impact stream to a 60° wide fan spray
A narrow stream has high impact force on the clean-
ing surface and results in maximum deep cleaning in 
a concentrated area . However, this narrow high impact 
spray must be used cautiously, as it may damage some 
surfaces (fig . 3b) .
A wide fan pattern will distribute the impact of the 
water over a larger area, resulting in excellent cleaning 
action with a reduced risk of surface damage, Large sur-
face areas can be cleaned more quickly using a wide fan 
pattern (fig . c) .

Nozzle cleaning instructions

A clogged or partially clogged nozzle can cause a sig-
nificant reduction of water coming out of the nozzle 
and cause the unit to pulsate while spraying . To clean 
out the nozzle:

1 .  Turn off and unplug unit .
2 .  Turn off water supply . Relieve any pressure trapped 
in the hose by squeezing trigger 2-3 times .
3 .  Separate lance from gun .
 4 .  Rotate nozzle to the narrow stream setting . This 
opens up the fan blades .
 5 .  Using included tip cleaner, or an unfolded paper 
clip, insert wire into the nozzle hole and move back and 
forth until debris is dislodged .
6 .  Remove additional debris by back-flushing water 

through the nozzle . To do this, place end of a garden 
hose (with water running) to end of nozzle for 30-60 
seconds .

EXPLOITATION

When spraying water against a surface, maximum im-
pact is generated when the water strikes the surface 
“head on .” However, this type of impact tends to cause 
dirt particles to imbed in the surface, thereby prevent-
ing the desired cleaning action .
The optimum angle for spraying water against a clean-
ing surface if 45 degrees (fig . 10) . 
Spraying water against a surface at this angle provides 
for the most beneficial impact force combined with ef-
ficient removal of debris from the surface .
Another factor that determines the impact force of the 
water is the distance from the spray nozzle to the clean-
ing surface . The impact force of the water is increased 
as the nozzle is moved closer to the surface .

DETERGENTS

The use of detergents can dramatically reduce clean-
ing time and assist in the removal of difficult stains . 
Some detergents have been customized for pressure 
washer use on specific cleaning tasks . These detergents 
are approximately as thick as water . The use of thicker 
detergents, such as dish soap, will clog the chemical 
injection system and prevent the application of the de-
tergent (fig . 11) .
The cleaning power of detergents comes from apply-
ing them to a surface and giving the chemicals time to 
break down the dirt and grime . Detergents work best 
when applied at low pressure .
The combination of chemical action and high pressure 
rinsing is very effective . On vertical surfaces, apply the 
detergent starting at the bottom and work your way 
upward . This will prevent the detergent from sliding 
down and causing streaks . High pressure rinsing should 
also progress from the bottom to top . On particularly 
tough stains, it may be necessary to use a brush in com-
bination with detergents and high pressure rinsing .

NOTE: 

Use only detergents formulated for 

pressure washes .

WATER SUCKING FUNCTION

•  Connect the hose to high pressure mashine and con-
nect it to the water tank;
•  Turn on high pressure mashine;
•  PUSH and keep the trigger of gun some time for filled 
water pump;
•  Lets release the trigger of gun and connect necessary 
nozzle;
•  High pressure mashineIS ready to work .
