WORKING PRINCIPLE
The DRAGON unit is dened “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
reduction 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 exible 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.

The high speed of travel of the product in the hose
can create static electricity through discharges
and sparks. It is suggested to earth the equipment.
The pump is earthed through the earth cable of
the supply.
The gun is earthed through the high pressure
flexible hose.
All the conductors near the work area must be
earthed.
Avoid approaching too much to the pump piston
rod when the pump is working or under pressure.
A sudden movement of the piston rod can cause
wounds or finger squashing.
Never spray over flammable products or solvents
in closed places.
Never use the tooling in presence of potentially
explosive gas.
Always check that the product is compatible with
the materials composing the equipment (pump,
spray gun, flexible hose and accessories) with
which it can come into contact. Never use paints
or solvents containing Halogen Hydrocarbons
(as the Methylene Chloride). If these products
come into contact with aluminium parts can
provoke dangerous chemical reactions with risk
of corrosion and explosion.

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
electronic equipment, wait 5 minutes after having disconnected
the power supply cable, so that the electricity stored in the con-
densers while working can be dissipated.
Also check the condition of the earth cable to avoid any risk of
shock.
DRAGON equipment is tted with an additional external earth
cable that is connected to the stem on the pump unit be means
of a specic clamp (H4), in order to protect the operator against
any risk of static or electric shock.

SPRAY ADJUSTMENT
• Slowly turn clockwise the pressure control knob (I4) to reach
the pressure value in order to ensure a good atomization of
the product.
The valve (I5) 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.
• 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.
I4

I2
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 (I5) opens automatically eliminating
part of the product from the recirculating tube (I6).
Then it closes so as to go back to the first wor-
king conditions.
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.

Make sure that the machine sucks in clean
washing liquid. Allow the cleaning liquid to
discharge into another container and do not mix
it with the cleaning liquid still to be used.
We recommend circulating the cleaning liquid for
at least 15 minutes.
For disposing of the washing liquid, see the
requirements laid down in the Standards in force
in the country in which the equipment is used and
act accordingly.
The Client is solely responsible for any irregular
action taken before, during, or after disposing of
washing liquid, or in interpreting and applying the
current Standards in this regard.
Hold the spray gun against the edge of the metal
contained (J5).
