WORKING PRINCIPLE
The DRAGON unit is defined “electric piston pump”.
An electric piston pump is used for high pressure painting without
air (from this process derives the term ”airless”).
The pump is controlled by an electric motor coupled with a re-
duction gear.
A cam shaft and a connecting rod allow to obtain the reciprocating
motion necessary to the working of the “pumping group” piston.
The piston movement produces a “vacuum”.
The product is sucked, pushed towards the pump outlet and then
sent to the gun through the flexible hose.
An electronic device located next to the reduction box, is used to
regulate and control the pressure of the material leaving the pump.
When the pump reaches the set value, the motor stops and starts
again when the value decreases.
A safety valve avoiding overpressure, guarantees the total reliability
of the equipment.

PROTECTION OF HEARING IN CASE OF WORK
NEAR THE PLANT.
Never attempt to tamper with the calibre of in-
struments.
SETTING-UP
CONNECTION OF THE FLEXIBLE HOSE TO THE GUN
• Connect the high pressure flexible hose (F1) to the pump
(F2) and to the gun (F3) , ensuring to tighten the fittings (the
use of two wrenches is suggested) .
NEVER use sealants on fittings’ threads .
It is ADVISED to mount a high pressure manometer at the
pump outlet (see on page “Accessories”) to read the product
pressure .
• It is recommended to use the hose provided with the standard
kit (ref.18036).
NEVER use a damaged or a repaired flexible hose.
• NEVER SPRAY OVER FLAMMABLE PRODUCTS OR SOL-
VENTS IN CLOSED PLACES.
• NEVER USE THE TOOLING IN PRESENCE OF POTEN-
TIALLY EXPLOSIVE GAS.

CHECK ON POWER SUPPLY
• Check the mains voltage corresponds to the equipment’s
rating.
Make sure that the electrical system is earthed and
complies with regulations.
• The supply cable is provided without plug.
Use a plug which guarantees the plant earthing.
Only a technician or a skilled person should perform the
connection of the plug to the electric cable.
To avoid electric shock when disassembling or checking the elec-
tronic equipment, wait 5 minutes after having disconnected the
power supply cable, so that the electricity stored in the condensers
while working can be dissipated.
Also check the condition of the earth cable to avoid any risk of shock.
DRAGON equipment is fitted with an additional external earth
cable that is connected to the stem on the pump unit be means
of a specific clamp (F4), in order to protect the operator against
any risk of static or electric shock.
Should anyone use an extension cable between
the tooling and the socket, it must have the same
characteristics as the cable supplied (minimum
diameter of the wire 4 mm2) with a maximum leng-
th of 50 mt. Higher lengths and lower diameters
can provoke excessive voltage falls and also an
anomalous working of the equipment.
Before carrying out any checks on the machine
(maintenance, cleaning, or replacing parts) switch
off the machine and wait until it has stopped
altogether.
While checking stay away from electrical or moving
parts to avoid any risk of shock or crushing of hands.
WARNING :
• DO NOT modify the plug for the earth socket
in any way.
• ONLY use electrical connections that are
earthed.
• Make sure that any earth extension cords are
in good condition.
• ONLY use three-core extension cables.
• Avoid direct contact with the rain. Keep the
equipment in a dry place.

SPRAY ADJUSTMENT
• Slowly turn clockwise the pressure control knob (G4) to reach
the pressure value in order to ensure a good atomization of
the product.
NEVER point the spray gun at yourselves or at
other people. The contact with the casting can
cause serious injuries.
In case of injuries caused by the gun casting, seek
immediate medical advice specifying the type of
the product injected.
The valve (G2) serves two purposes:
• Safety: It opens the passage at pressure peaks exceeding
280÷300 bar;
• Regulation: It returns the working pressure to 230 bar and
levels out the hydraulic operating hysteresis.
Safety valve: when working at the maximum pres-
sure available, releasing the gun trigger sudden
increases of pressure can occur. In this case, the
safety valve (G5) opens automatically eliminating
part of the product from the recirculating tube (G6).
Then it closes so as to go back to the first working
conditions.
• An irregular and marked spray on the sides indicates a low
working pressure. On the contrary, a too high pressure causes
a high fog (“overspray”) and waste of product.
• In order to avoid overthickness of paint, let the gun advance
sideways (right-left) when spraying.
• Always paint with regular parallel bands coats.
• Keep a safety and constant distance between the gun and the
support to be painted and also keep yourselves perpendicular
to it.
