distance of 16 yd . (15m) away .
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 .
