• Do not alter the original diameter of the spray head
nozzle.
• Do not leave the high pressure cleaner unattended.
• Do not move the high pressure cleaner by pulling on
the electrical cable.
• All electrical conductors MUST BE PROTECTED against
the water jet.
• The high pressure cleaner MUST ONLY BE CONNECTED
to a correctly earthed power supply.
• The high pressure may cause materials to bounce o
surfaces at speed; therefore protective clothing and
safety goggles MUST BE WORN.
• Before doing work on the cleaner, REMOVE the plug.
• Before pressing the trigger, GRIP the gun rmly to
counteract the recoil.
• Maintenance and/or repair of electrical components
MUST be carried out by qualied sta.
• DISCHARGE residual pressure before disconnecting
the high pressure cleaner hose.
• Before using the high pressure cleaner, CHECK every
time that the screws are fully tightened and that there
are no broken or worn parts.
• Only USE detergents which will not corrode the coat-
ing materials of the high pressure hose/electrical cable
• ENSURE that all people or animals keep a minimum dis-
tance of 16 yd. (15m) away.
ASSEMBLY
• Connecting water hose to inlet rst,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 forget
to press the in electronic control center to start the ma-
chine.
• The electronic control center has three pressure modes
for users to choose. There are soft, medium and strong
mode.The pressure depends upon which attachment 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 - but-
ton 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.
PREOPERATION
Adjusting fan pattern
Water can be sprayed either with a narrow jet or fan-
shaped. The kit includes 4 nozzles with a non-adjustable
spray angle of 0, 15, 25, 40. Install the required nozzle
before starting work, depending on the task.
Nozzle cleaning instructions
A clogged or partially clogged nozzle can cause a signif-
icant reduction of water coming out of the nozzle and
cause the unit to pulsate while spraying. To clean out the
nozzle:
1. Turn o and unplug unit.
2. Turn o 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-ushing 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 preventing
the desired cleaning action.
The optimum angle for spraying water against a cleaning
surface if 45 degrees.
Spraying water against a surface at this angle provides
for the most benecial impact force combined with e-
cient 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 cleaning
time and assist in the removal of dicult stains. Some de-
tergents have been customized for pressure washer use
on specic cleaning tasks. These detergents are approx-
imately 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 detergent.
The cleaning power of detergents comes from applying
them to a surface and giving the chemicals time to break
down the dirt and grime. Detergents work best when ap-
plied at low pressure.
The combination of chemical action and high pressure
rinsing is very eective. On vertical surfaces, apply the
