out pressure is 125 PSI or lower.
Adjusting Only Cut-Out Setting
If only the maximum tank pressure setting needs
to be adjusted, then follow these steps. Keep
in mind that the allowable pressure differential
between cut-in pressure and cut-out pressure
must be kept between 30–40 PSI. Exceeding this
range can cause the compressor to overheat.
To adjust cut-in/cut-out settings:
1. Operate compressor and record cut-in and
cut-out pressures.
2. DISCONNECT MACHINE FROM POWER!
— Turn screw half turn clockwise to increase
