Increased hazard caused by short spray equipment (less than 750 mm from the
handle to the nozzle)! Never direct the jet against parts of the body! Protect
yourself from any particles splashing back against you!
Ensure you connect the machine to the correct main supply voltage, as specified
by the manufacturer. The machine may only be connected to a correctly
installed plug socket. When connecting extension cables, ensure you are using
cable with proper minimum cross-sections. The machine must not be started if
any electrical component or accessory (cable, plug, switch etc.) is defective.
Only qualified personnel must carry out all electrical repairs.
Use only watertight cable, plugs and sockets. Any electrical installation should
be made only by a qualified electrician.
Τhe machine must be equipped with certified safety equipment at 500 bar.

OPERATIONS MANUAL Rev. 1.4
Always check and ensure that the machine and its accessories (hoses, cables,
fittings, spray handle, nozzle etc.) are in good working condition before start-up.
The maximum permissible pressure and temperature are printed on the high-
pressure hose. In case of damage, replace immediately with original approved
hoses.
If during operation you observe any leakage, abnormal noise or any other
malfunction, stop the machine and get it serviced.
You should not attempt to repair and reuse damaged high-pressure hoses.
You should only use original spare parts and accessories.
You should carry out only the maintenance works described in this manual and
use only original parts approved by the manufacturer.
Do not make any modifications to machine and ensure it is regularly serviced as
per its maintenance schedule.
Repair works to be carried out by qualified personnel only.
Never suck up solvent liquids such as thinners, petrol or oil as the resulting spray
is highly inflammable, explosive and toxic.
Always ensure the machine is placed in a stable position and cannot move.
Do not operate the machine without water or with insufficient quantity of
water, as such shortages may result in damage of the pump.
Do not cover the machine and ensure adequate air circulation.
Always store the machine in places where it will not be exposed to frost.
Use only original spare parts for maintaining the machine. Repairs should be
done only by qualified personnel.
After works, the machine should be stored not being exposed to harsh and
corrosive environment and secured against unauthorized use.
Never exceed the maximum working pressure of the machine!

start up, operations and maintenance of the machine. It has to be therefore read carefully by the
operator and should always be on site.
Attention
ABSOLUTELY NO PERSON OR ANY BODY PART SHOULD BE BETWEEN THE
MACHINE/SPRAY LANCE AND THE TARGET AREA FOR CLEANING WHILE THE MACHINE
IS IN OPERATION. THERE IS NO SAFE DISTANCE FOR TOUCHING OR FEELING THE HIGH-
PRESSURE WATER JET WITH HUMAN BODY PARTS.

OPERATIONS MANUAL Rev. 1.4
Water quality requirements
The environment temperature when the high-pressure cleaner operates should be min +4°C
and max + 40°C.
Notes on the requirements for the water used.
The STANDARD pumps work with clean, soft water, at a maximum temperature of 40˚C, and only for
short periods, up to 60˚C.
Temperature
Max. 40° C inflow temperature.
pH
The pH value must be between 6.5 and 9.5.
Conductivity
Conductivity at 20°C must be below 2000 μS/cm.
Purity
The water must be free of abrasive and particulate materials.
NOTE:
It is the responsibility of the operator to ensure that the water quality is per requirements. Prolonged
usage of the machine with poor water quality will lead to severe damages of the machine.

Description and Function of the Safety Installations
•Unloader Valve for Bypass Mode
The high-pressure valve limits the operating pressure. When the maximum operating pressure is
exceeded or the handle is closed, the unloader valve administrates the water over a bypass connector
back to the water tank through the water diffuser.
•Safety Valve
The safety valve limits the maximum operating pressure to 550 Bar. If the maximum operating pressure
exceeds the specified limit due to closing of the spray handle the unloader valve receives a switching
surge and the channels the water through its bypass.
In case of excessive pressure more than the permittable limit for any other reason, the safety valve is
activated and allows to leak through it, thus reducing the pressure.
•Protection against freezing
Freeze can destroy equipment which has not been emptied completely of water.
To protect the machine against frost it must be stored with antifreeze fluid filled inside the water tank.
Fill approximately 4lt into the water tank and run the machine without high pressure hose in order to fill
the pump with antifreeze liquid.
In order to reach the antifreeze in all the parts please start the machine 2-3 times, till antifreeze comes
out of the high-pressure outlet.

OPERATIONS MANUAL Rev. 1.4
Operating the machine
Check points before start-up
•Place the high-pressure cleaner on a plain and secure it against rolling.
•Check the oil level of the high-pressure pump. If it is too low, refill oil.
(Pump oil specification: SAE 15W40 ISO VG100 DIN 51524)
•Maximum oil level from the high-pressure pump is on the top mark of
the oil dip stick or in the middle of the window.
•Do not overfill the pump with oil.
•Electrical mains voltage/frequency should be the same with the electrical data of the
machine. Recommended ship-side breaker: 50A, class D or K.
•Check general condition of the machine and accessories to be in good order (cable,
power & water connectors, hoses, handle, lance, nozzle etc.)
Attention: Use only original nozzles with the machine.
Water connections
Connect the water intake hose on the high-pressure cleaner.
Connection installed ¾’’ with GEKA coupling.
Always secure sufficient water supply, keep it well above the operational water flow. Minimum input
feed water requirement is an average of 22 liters/minute or 1320 liters/hour
Insufficient water supply will cause machine to stop.
Connection of high-pressure hose
Screw the female M22 coupling to the high-pressure outlet of the machine, use two spanner size 27 to
fasten. The male 3/8” coupling must be screw to the inlet swivel of the spray handle, use one spanner
size 22 and one 24.
Electrical connection
The voltage shown on the motor plate should correspond to the source.
1. 380 V/50 Hz/3 ph – max 50 A
2. 440 V/60 Hz/3 ph – max 50 A
Use the correct dimension of electric cable wire in case you connect an extension cable.
For cable extension lengths up to 50mtr, the cross section of the wire to be used is
6mm2.
