Question about Dewalt & 2HP Hand Carry Heavy Duty Electric Air Compressor
I don't have the emglo version. mine just says dewault on it. I have opened up the whole case and got to where the wires connect to the pressure switch, but there are not any screws to adjust on it. Am I missing something? I don't see any set screws anywhere on it to adjust.
Looking at your manual, instead of the actual item since I don't have one, I see 312, 329 and 314. It is possible that 312 the switch is shorted causing the pump to run to pop off and beyond. Item 14 is the pop off valve and if the numbers indicate anything, it is a 175 PSI pop off and is going off early. The switch doesn't have any indication of pressure rating.
The screw and bracket that mounts on the switch may be a pressure adjustment but hard to tell remotely.
Some units like this don't have adjustments, they just pump to a predetermined pressure and stop, being determined by the pressure switch and if the switch fails, a pop off will prevent over-pressuring the tank or system.
If you determine that the screw and bracket do not make an adjustable pressure switch, replace the switch with a like on or one that you can adjust in the range you need. Also if the pop off is going off early, replace or if possible, clean it, they can become dirty with rust.
Is possible that the screw fell out of the pressure switch rendering it "broken" until you put it back in....

150 is your cutout pressure. It's the factory setting and is not a problem. But, It appears you have a pop off (safety) that is set for 125 psi, So, If you want 150 psi, the pop off needs to be adjusted. If you want 125 the the cut out switch needs the adjusting. The setting. More than likely the 125 psi pop off valve is correct and the switch needs to be adjusted down below the pop off pressure. To sdjust the switch, remove the cover of the box the cord comes out of.Adjust using the screw(s). There should be one for cut in and another for cutout pressuressures. The cut in pressure should be 90 psi and the cutout should be at 125 psi.If the pop off valve blows off at 125, It needs either replace or adjusting. It's best to replace it.since the spring inside has lost tension. You will be constantly adjusting it otherwise. Good Luck -Ned_ Take caution not to get your tool or fingers into the electrical in the switch box.
