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.

SISTEMA ANTIGELO
The machine is equipped with an anti-freeze
system that allows it to work even at very low
temperatures. However, after a few minutes of
operation, the upper metal outer surface cools
dramatically. Avoid touching the area indicated.
Contact of the skin with the low-temperature area
may cause frostbite. Common working clothes
and leather gloves provide adequate protection.
SIf the product to be used is toxic avoid inhalationa
and contact, by using protective gloves, goggles
and suitable face shiedls
Take proper safety measures for the protection
of hearing in case of work near the plant.

SETTING UP
TYPICAL INSTALLATION
CONNECTION TO THE FEED AIR
 For pump feed use a hose with an internal diameter no
lower than 20 mm.
Install at the pump inlet an air pressure regulator
(it is suggested complete with condensate filter
and lubricator). The outlet pressure of the material
is 23 times (OMEGA 23:1) or 30 times (omega 30:1)
the inlet pressure of the pump feed air. Therefore,
it is extremely important to adjust the value of the
feed air pressure.
