regulator?
by: Doug in s.d.ca.

If by that you mean the regulator - that has nothing to do with cut-out.

Sounds like you changed tanks, and you need and want it to shut off around 140?

If so, you need to adjust the pressure switch, if that's possible, or get a new pressure switch that has the range you need.

167320 pressure
by: Bill

Your tank gauge shows the pressure in the tank.

The regulator gauge shows the pressure setting on the regulator.

If you turn the regulator knob to lower the pressure, and the pressure display on the gauge does not change, odds are good that the gauge is frozen or the regulator isn't working.

Since the cutout pressure of this model is 165 PSI - I believe - are you saying that it runs and runs but the compressor tank pressure doesn't get past 140 PSI?

That being the case, see the troubleshooting page for links to information on why compressors run but don't build full pressure.
