WORKING PRINCIPLE
The THOR 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
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 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.

THOR 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 len-
gth of 50 mt. Higher lengths and lower diameters
can provoke excessive voltage falls and also an
anomalous working of the equipment.
• 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
electronic 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.
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 mo-
ving 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 (G5) to reach
the pressure value in order to ensure a good atomization of
the product.
The valve (G6) serves two purposes:
• Safety: It opens the passage at pressure peaks exceeding
280-300 bar;
• Regulation: It returns the working pressure to 250 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 (G6) opens automatically eliminating
part of the product from the recirculating tube
(G7).
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.
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.
