The high pressure cleaner is now ready for operation. The spray-gun lance will experience a
recoil force during operation –therefore keep a firm grip with both hands on the Spray-gun
handle and the lance. Press the trigger and start cleaning.
-Pressure can be regulated by adjusting the knob on the spray-gun lance.
-When using the chemical injector, pressure must be adjusted to low.
Make sure your local power supply specifications are in accordance with the
motors requirement. Refer to the ID-plate on the machine. Do Not run the High
Pressure Cleaner without sufficient potable water supply as it can cause
cavitation and serious damage to internal pump parts. Do not let the machine
recycle the water (running with Spray-gun trigger not activated) for more than
a few minutes as this can cause serious damage to the seals.
Starting up for the 1st time
1. Allow water to flow within the machine for about 3 to 5 minutes without turning on the
machine to allow any dirt or air to be vented out from the delivery outlet.
2. Ensure the mains voltage is the same as that of the machine printed on the technical data
plate.
Failure to comply with the regulations stated above, manufacturer declines all
responsibilities for the staff and provides no warranty.
Water Connection
1. Connect the inlet hose to the water mains using the
High Pressure hose which comes together with the
machine. (Max Pressure: 200Bar).
Filling up with Fuel
1. Fill the tank with the Diesel.
2. Avoid running the machine when diesel tank is empty in
order not to damage the fuel pump.
CAUTION
NOTE

Subject
Matter / Procedure
Cleaning
Use a damp cloth to wipe the cabinet. Do not use detergent cleaning
chemicals.
Notice: To prevent electrical shock. DO NOT SPRAY DIRECTLY
UPON THE MACHINE WITH HIGH PRESSURE.
Occasionally clean the fan cover of the blower to ensure sufficient
airflow.
Do NOT operate the machine with damaged or removed fan cover.
Inspection
To prevent electrical shock and spills of leaking water. Check
electrical cord and high-pressure hose for wear and cracks. Keep
coupling parts free of dirt to ensure long life of O-ring seals
preventing water leak.
Notice: To prevent damage on hoses and cord, be careful not to have
them run over by heavy vehicles or squeezed in door openings etc.
Replace if necessary.
Storage
Be sure the cleaner is kept frost-free, if not possible flush the inlet of
the cleaner with antifreeze fluids.
Depending on water quality,
clean the strainer in the water
tank regularly.
Depending on Fuel quality
clean the fuel filter regularly.

3. Maintenance and Troubleshooting
HB-200 V00 Page 10
Troubleshooting
Symptom
Cause and Rectification
When the main
switch is turned on
the high-pressure
cleaner will not run.
Fault somewhere in the power supply.
Make sure the socket is inserted correctly. Inspect cord for cracks
and wears. Check if fuse is blown, replace if necessary.
The blower motor
does not start.
Too low voltage.
Check the mains voltage.
Check the connection box voltage with a meter.
With the machine turned off, turn the motor, at the fan,
The pressure drops
and the high-
pressure cleaner
works irregularly.
The strain filter is clogged or the water supply from the tap is
insufficient.
Ensure sufficient water-flow through the cold water machine.
The boiler will not
burn
The fuel tank is empty. The fuel filter is clogged. The fuel nozzle is
clogged. The spark electrodes are worn or out of alignment. The
flame censor device is active. The glass between the flame censor
and the boiler is dirty.
Fill up the fuel-tank. Clean or replace the fuel filter. Clean or
replace the fuel nozzle. Adjust or replace the spark electrodes.
Reset the device by pushing the reset button at the control panel.
Clean the glass between the censor and boiler.
The high-pressure
cleaner does not suck
chemicals
The chemical container is empty. The high-pressure cleaner has
not been set to low-pressure (on the double barrel lance cock).
The low-pressure nozzle is clogged, or partly clogged. The non-
return valve of the chemical injector is stuck.
Ensure the chemical container contains sufficient fluid for proper
suction.
Set the spray-lance to low pressure by turning the cock on the
lance counter-clockwise.
Clean or replace the low-pressure nozzle.
Clean, correct or replace the non-return valve of the chemical
injector.
For any further inconveniences, not mentioned in this user guide or any
damages of the machine, we strongly suggest you to make contact with your
