10gal 125 psi CP compressor will not repressurize

It will start and run, to build pressure till 125. Then it shuts down, like it should.


As I use tool, it will not restart to pressurize tank back.

I need to run out of pressure almost completely.
Then, move switch lever to Off. Then, move it back to On. After that, red reset button pops up. Then, press that button - and compressor will start and work again.

It actually did this from brand new. I unfortunately had it in the box too long, till I got to it. It's out of return policy.

...probably is the problem.

It may be plain bad, or with luck, just gunked up. I'd take it off and look to see if it's repairable.

It could also be the unloader, but without a model number, I don't know if it actually has one. Some of these just have a small hole in the line somewhere to relieve the pressure.

Good luck.
