Anyway - it has no labelling on it whatsoever, so I have no idea who made the thing. It resembles this one:
I can load it with what its gauge says is 100PSI, but I can get nothing out of it. Obviously I am forgetting what to turn or otherwise operate to make it release its air. I have a hose connected (with a quick disconnect) and a trigger-controlled nozzle. I have two nozzles, and have tried both. I have tried the hose with no nozzle. I have backed off a little on a 1" knob, thinking that would release the air. Nothing.
I told you it was dumb. I can't find my old manual nor can I find same on the web.
Whar have I forgotten?
