7. Connect machine to power, start compres-
sor, and cycle compressor through cut-in/
cut-out pressures. If compressor does not
automatically turn
OFF at 150 PSI, turn
machine
OFF before pressure reaches 155
PSI. Adjust pressure switch settings until cut-
out pressure is 150 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 only cut-out setting:
1. Operate compressor and record cut-in and
cut-out pressures.
2. DISCONNECT MACHINE FROM POWER!
Releasing air through safety relief valve
can be extremely loud. Protect hearing with
ANSI-approved hearing protection while
performing following step.
3. Use safety relief valve to reduce tank pres-
sure to less than 10 PSI.
4. Remove Phillips head screw shown in
Figure 32 to remove pressure switch.
5. Adjust screw shown in Figure 33 to change
maximum tank pressure setting.
— Turn screw half turn clockwise to increase
tank pressure.
— Turn screw half turn counterclockwise to
decrease tank pressure.
