1. The compressor is controlled by pressure switch when normal
working. It can be stopped automatically as pressure increasing to the
maximum and restart as pressure decreasing to the minimum. The rated
pressure has been adjusted when produced. Don’t change it carelessly.
As soon as motor switched
off, the compressed air in
the discharge pipe should be
released through the release
valve under the switch. This
is the necessary condition for
restart, or the motor will be
damaged. The rated pressure
can be adjusted by turning
bolt of the switch (Fig.3).
2. The output pressure of
compressed air can be adjusted by regulating valve. Pull up the knob of
regulation valve and turn it clockwise to increase the pressure (Fig.3).
