OPERATION AND ADJUSTMENT

1. The compressor is controlled by pressure switch when normal working. It can

be stopped automatically as pressure increasing to the max and restart as pres-

sure decreasing to the min. The rated pressure has been adjusted when pro-

duced. 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 the adjusting 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 or counterclockwise to

increase or decrease the pressure (Fig.3)

3. Then the compressor in running need be stopped, only set the knob of pres-

sure switch in positing off.
