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.

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.
