is situated on the foam regulation control panel. In this way the compressor starts
working and the pressure inside the air tank starts increasing. During this step, the arrow
of the manometer indicating air pressure moves towards higher values.
10. Wait for about 1 minute, without spraying with the lever of the foam spray accessory, until
the pressure of the air reaches such a value that the compressor stops. The tuning of the
machine during our tests is such that the compressor stops when the manometer
indicates about 4 bars.
