To adjust cut-in/cut-out settings:
1. Operate compressor and record cut-in and
cut-out pressures.
2. DISCONNECT MACHINE FROM POWER!
Adjusting Cut-In/
Cut-Out Settings
The pressure switch ensures the compressor will
turn
ON when the tank pressure drops to approxi-
mately 95 PSI (cut-in pressure), and will turn
OFF
when the tank pressure reaches 125 PSI (cut-out
pressure). Should the pressure switch fail to turn
OFF the machine, the safety relief valve will open
shortly after the pressure exceeds 125 PSI and
prevent over-pressurization.
Cut-in and cut-out settings have been
factory set at proper PSI range. Only adjust
pressure switch settings if compressor
is cutting-in or cutting-out at incorrect
pressures. Tank could burst if filled with
more pressure than it is designed for.
Eye injury hazard! Always
wear safety glasses when
handling pressurized air
system.
