It has a pressure valve, that's all.

I was facing this exact same issue. My dewalt compressor was spitting milky oil, and then suddenly stopped working but then I found this troubleshooting guide which really solved my issue: https://aircompressorinsider.com/air-compressor-problems-and-solutions/ Your mentioned issues were at somewhere around number 60-65, I dont exactly remember it now :)

you may be using more air that unit can supply. This is a very common error. it is only 5 cfm which is small. Call Whitton Supply Co. or visit our local Oklahoma City showroom (405) 236-5561.

there is not one.

pin has debris /bent and needs lube or retractor needs repair

There is a ground fault in that case. If you are in need to ask this sort of question, I recommend the services of a qualified electrician.

THERE IS NONE

There is no reset button for the compressor, if the compressor won't start check the valve is not open, also check the outlet power, Shut the drain valve at the bottom of the tank if it's open

Likely nothing special just different setting from factory?

sounds like you ran it off level and siexed the pump

What? If it won't shut off when it trips the limit valve. You need to replace the pressure switch.

Valve plate

Not enough volume... if psi is good just increase the size of the line.

check your regulator to see that 80 is what the gun is receiving and if it is move to 90 psi

The box store pumps are usually sandborn pumps. I would find the model number and brand on the pump and go from there.

Try rearranging all the parts of the gun if possible. Clean them and try using them again , It should work.

You will have to get a new gasket. I had the same problem but I had drop my gun.
