6. Install pressure switch cover.
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 125 PSI, turn
machine
OFF before pressure reaches 130
PSI. Adjust pressure switch settings until cut-
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. Perform Steps 1
–4 of Adjusting Cut-In/Cut-
Out Settings on Page 35.
2. Adjust screw shown in Figure 46 to change
maximum tank pressure setting.
— Turn screw half turn clockwise to increase
tank pressure.
— Turn screw half turn counterclockwise to
decrease tank pressure.

Aligning
Motor Pulley to
Pump Flywheel
Pulley alignment is an important factor in power
transmission and belt life. The motor pulley should
be parallel to the pump flywheel and in the same
plane (coplanar) for optimum performance.
The motor pulley alignment can be adjusted by
loosening the set screws that secure it to the
motor shaft.
