7. OPERATION AND ADJUSTMENT

(1) The compressor is controlled by pressure switch when normal working. It can be stopped automatically as pressure
increases to the maximum and restart as pressure decreases 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 restarting, or the
motor will be damaged. The rated pressure can be adjusted by turning the adjusting bolt of the switch (Fig,2).
(2) The output pressure of compressed air can be adjusted by regulating valve. (Fig. 2).
(3) When the compressor in running and needs to be stopped, just set the pressure knob to off position.
