When the upper calibration value (set by the manufacturer) has been reached, the
compressor stops, venting the excess air present in the head and in the delivery pipe
through a valve located under the pressure switch. This facilitates subsequent restart due
to the absence of pressure in the head. When air is used, the compressor restarts
automatically when the lower calibration value is reached (2 bar between upper and
lower).
The pressure in the receiver can be checked on the gauge provided (fig. 8).
The compressor continues to operate according to this automatic cycle until the switch of
the pressure switch is turned.
Always wait at least 10 seconds from when the compressor has been switched off before
restarting this.
All compressors are fitted with a pressure reducer. Operating on the knob with the tap
open (pulling it up and turning it in a clockwise direction to increase the pressure and in a
counterclockwise direction to reduce this fig. 9a), air pressure can be regulated so as to
optimize use of pneumatic tools. After setting the value required, push the knob to fasten
this (fig. 9b). On some versions, the ring-nut underneath must be tightened to fasten the
knob (figures 9c-9d).
The value set can be checked on the gauge.
Please check that the air consumption and the maximum working pressure of the
pneumatic tool to be used are compatible with the pressure set on the pressure regulator
and with the amount of air supplied by the compressor.
Always pull out the plug and drain the receiver once you have completed your work
(figures 10-11).

ATTENTION! The sound power pressure may exceed 85 dB(A), in this case
individual hearing protection must be worn.
9 MAINTENANCE
BEFORE CARRYING OUT ANY OPERATION, ALWAYS PULL OUT THE PLUG AND
DRAIN THE RECEIVER COMPLETELY (figures 10-11)
Check that all screws (in particular those of the head of the unit) are tightly drawn up
(torque 10 Nm = 1.02 Kgm). The check must be carried out prior to the first compressor
starting.
