2.1 MACHINE SET UP

GB
Install the compressor on a flat surface, in a suitably sized room, well ventilated and not
wet, where the temperature is not likely to rise above 40°C. If there is not enought air
ventilation, install a suitably sized exhauster or fan.
The power supply voltage must be the same indicated on the data label: 230V/50-60Hz
(115V/60Hz) and the socket must be 2 pole+ground type.

2.2 OPERATING INSTRUCTIONS

Always use your compressor on a flat surface.
The start switch is situated on the cover of the pressure switch.
Turn the switch to position "0" (Fig.1).
Insert the plug into the socket and start the compressor turning the switch to position
"1".
The compressor working process is automatic.
The pressure switch stops the compressor when the pressure in the tank reaches the
maximum value allowed (8 bar=116psi standard) and starts it again when the pressure
drop to the minimum value (6 bar=87psi standard).
Adjust the outlet air pressure operating on the reducer-filter (Fig.2)
Pressure is shown on the gauge placed on one side of the regulator.
Pressure adjustment (fig. 3):
1. adjustment of max. pressure (cut out)
Max pressure can be adjusted through the two screws "A" and "B".
Rotate the screws "A" and "B" clockwise in order to increase pressure.
2. adjustment of differential pressure (cut in).
Differential pressure can be adjusted through the screw "C".
Rotate the screw "C" clockwise to reduce differential pressure.
I WARNING!
Pressure regolation must be carried out by skilled personnel only.
If the pressure switch does not work
(overpressure), the safety valve will automatically operate and open when the pres-
sure exceeds the max. setted value.
