I own a Bostitch 6-gallon compressor – reconditioned. Using it for the first time.

The regulator knob will not turn – not even a little. Seems really frozen – or something.

The compressor DOES work. I’ve nailed some things with it. Now I just want to regulate it. Ideas?

If pushing in or pulling out on the regulator knob doesn’t allow you to turn it to adjust the downstream air pressure, then I suspect you’ll be adding a new air regulator soon.

What pressure is showing on the regulator gauge? If the regulator is built in, and you are getting full pressure downstream from it, you can install a regulator at the end of the discharge coupler, and then put a coupler on the other side of it for the air line, and achieve the same results, as long as the first regulator is fully open.
