It never gets above 50psi.
Now, it doesn't shut off at 50psi. The motor keeps running and running (it's supposed to cut off at 125psi). It doesn't seem to strain at all and I can't detect any leaks. Also odd is the fact that it gets up to 50psi quickly and just stays at that pressure. It's not like it seems to be having a hard time getting there. The pressure just immediately levels off as if a valve opened. However I can't detect any air escaping at 50psi.
If I shut off the compressor it holds 50psi indefinitely. No leakage at all.
Any ideas? Why would this compressor just STOP? Is there something I should know that I'm missing?
I don't know if I can take it back (it's used). I just want to know if there's a setting or valve which can account for this.
