When you unplug, grasp the plug instead of the cord.
Only use the power cord which with rubber insulation enclosure or protection enclosure.
Keep the plug and hose in dry place.
To prevent the maximum operating pressure, the outlet hose should be at least 9.8FT/3M
long.
Do not use the pressure cleaner in inflammable environment.
Take care of the kickback force and the sudden torque on the spray assembly when
opening the trigger gun. Always use two hands to grip the gun firmly before pressing the
trigger.
Only press the switch after the high pressure hose is tightly fixed.
Always wear protective clothing, glove and safety glasses. It’s forbidden to use the
machine bare-footed or when wearing a sandal.
By operation keep the hand away from the water jet and hose.
Sometimes the reflected water is also dangerous.
Do not direct the water to fire or hot equipment. Hot particles and steam are dangerous.
Do not use the pressure washer with inflammable or toxic liquids, corrosive detergents, or
any dangerous products.
Use only hand to squeeze the trigger, do not jam the trigger in the ON position.
Before disconnect the high pressure hose, turn off the machine first, then squeeze the
trigger until there is no more pressure in the system.
Do not bend, twist or fold the hose.
Use only original spar parts supplied from manufacturer.
A fluctuating or high water pressure shows signal of defect or accumulation of the calcium
in the hose. In this case turn off the machine immediately.

Do not run the cleaner without water which will cause damage to the cleaner.
Before starting the machine, fully open the water supply tap. Be careful not to bend the
hose.
When the machine hose or tube freeze in winter, do not use it. Before storing the water
must be drained from the machine. Always store the pressure washer in a secure dry and
frost protected place
Do not use the machine in a dirty place.
Put the machine on a flat surface.
The sea water is not suitable for using in this machine.
The appliance is not fit for long time industrial use.
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or capabilities, or lack of experience and knowledge, unless they have
been given supervision or instruction concerning use of the appliance by a person
responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
The function of Safety valve: when the pressure of the pump exceeds the Preset valve,
returns the excess fluid to the inlet system.
The function of pressure switch: When turn off a gun, pressure switch on the action, cut off
the power supply for protection operations.

ASSEMBLY STEPS
High pressure hose connection
Connect the pressure hose to the machine’s outlet, ensuring it is
connected firmly. See picture 1
Gun connection
Connect the gun lance(Fixed brush/turbo lance) to the gun stock. Turn the gun lance clockwise
until it locked in position. Connect the hose to the thread of gun stock by spanner. Check that
the seal ring is properly seated. See Picture 2
Picture 2
Inlet hose connection
Picture 1
1. Connecting water hose to inlet, make sure
it is connected firmly. Do not turn on the machine at
this moment.
2. Turn on the tap, ensuring the inlet water pressure
range is between 0.01Mpa and 0.3Mpa.
3. Pull the trigger till all the air is pushed out of
machine and water flows from the gun which
means the pump is full of water.
4. Then you can turn on the switch. See picture 3.

OPERATION
Gun operation
Adjust the water pressure and the shape of water column by changing the nozzle.
Picture 4
High/Low Pressure Operation
The nozzle controls the water pressure.
Attach the high pressure nozzle. Make sure the distance between the nozzle and the
workpiece is at least 11.8”/30cm.
NOTE: No detergent will be dispensed in high pressure mode
LOW Pressure Operation(for dispensing cleaning detergent)
Attach the high pressure nozzle. This is the required position to dispense the detergent from
the built in detergent reservoir.
NOTE: Detergent need to be diluted to achieve the most effective cleaning. It is
recommended to diulute the detergent in a suitable container to the requied
concentration before using

Switching off the appliance
1. Turn off the water supply at the tap.
2. Press the trigger to reduce the pressure in the appliance.
3. Pull out the water inlet hose, and then let the machine run a few seconds to drain the
water of storing in the pump.
4. Switch off the appliance and disconnect the electric plug from the power socket.
5. Detach the pressure hose. To drain the residual water, lift up the jet gun and squeeze the
trigger. See picture 6.
USER MAINTENANCE AND REPAIR
Disconnect from the electrical power supply before carrying out user maintenance.
Turn off the water supply at the tap and press the trigger to discharger the pressure.
Lubricate the fixing periodically using the lubrication oil.
When the water pressure is not consistent or too high, it shows the signal of defect hose
or accumulation of the Calcium in the nozzle.
Turn off the machine immediately.
Use the nozzle cleaner to clean the hose and the water inlet filter.
Change the defective filter.
Make sure that the machine is clean and clean the components when necessary.
Follow the operation-instructions for the different parts. Pluggable ring-nuts are used to
connect the gun, hose and other parts.
The seals of the ring-nut connections shall not be damaged
Turn the detergent tank and fasten it to the foam nozzle.
Connect the foam nozzle with the jet gun.
Turn on the machine. input the cleaning agent by a proportion of 1%. Warning: Use only
the cleaning agent supplied by the manufacturer or their after-sales service.
Keep the appliance safe and store them carefully in a secure dry place. Always store the
machine out of the reach of children.
