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.
PREOPERATION:
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.
