Could be piston O rings, worn cylinder line, worn reed valve-plate assembly, worn discharge check valve, leaking unloader valve. Need info if unloader is leaking or unloader tubing is leaking. The Cheapest and quickest is to remove valve plate assembly and inspect valve plate. Suction side should hold water and discharge valve should hold water placed on bottom of plate.

you're good to go! Plug and Play! :) Compressor Tank Pump Style Oil Free

it is possible that it is not the compressor but the breaker has reached it's end of life. I'd change it to eliminate that before throwing any more parts at the compressor. My suggestion anyway.

if you are using quick connects it is likely that you need to wrap with PTFE thread tape to ensure seal... If you aren't that would indicate a leak in the tool meaning the tool should be replaced...

Only the motor needs its feed connections changed from one voltage to the other. Someone knowledgeable about motors should do this. But, not all motors have multiple voltage capabilities. I have a Craftsman 2 HP compressor myself that only will run on 220. Check your manual on this. If you can't change the motor, it will probably be cost-effective to run a 220 line over buying a new motor.

Jam, low pressure

Does it start when the tank is pressurized?

I have worked on compressors from 15 PSI all the way up to 5000 PSI and everyone of the regulators I have seen bleed the pressure of when you dial it down and you can hear it.

You can download the manual in the following link. I think they charge a few dollars for it. https://www.searspartsdirect.com/partsdirect/user-manuals/900684253-CRAFTSMAN-ELECTRIC%20BRAD%20NAILER-manual

Shorten the cord or use a father one. Typical for voltage drop in loaded motors.

Is there pressure in the tank already? The reset is usually on the end of the motor. The pressure switch, a diaphragm pushes against an adjustable tension spring. Less spring tension cuts the motor out at lower pressure, more tension at a higher pressure. Has this adjustment been used? It may have a second adjustment, either nut or screw, that adjusts the pressure differential between cut in and cut out.

Usually there is a leak some where. turn off and watch pressure to see if it drops and listen for any air leak. you should not hear anything.

Have you tried oiling the unit. Sometimes putting a bit of 3 in 1 oil or wd 40 in the air intake will loosen the parts so they work correctly.

That motor has been discontinued. You might try and replace start capacitor and if it has run capacitor replace it also. From experience I found that is cheaper to junk unit and buy a new one. You wouldn't want spend a couple hundred dollars on motor.

Try carefully lightning the tubing nut to resale.

NO. If your tank leaks from pinholes you could try and braze the closed

possibly an installation problem most control units screw directly into the tank and the pressure is read directly to the diaphragm that controls the switching check if the bleeder line is supposed to be attached to the control unit at all unless you have a peculiar set up the compressor line goes to a nonreturn valve into the tank there is a relief valve in the tank that blows off when dangerous pressures are reached ( around 120 psi) there is a fitting where the control screws in and that reads tank pressure to control the on/off of the motor
