STUPIDITY ALERT: (if this narrative exposes what an idiot I am, please keep the abuse good-natured, LOL) I'm filling to an AirHog bottle via a double ended male connector. Once I reached pressure, I closed the bottle with compressor still running and blew the disc before I could open the bleed valve (like 2 seconds?). I guess the solution would be to shut down the compressor BEFORE closing the bottle. BUT I didn't want to do that for fear the compressor would get jammed by back pressure on the piston. I'm sensitive to this issue, because when the compressor was new it would freeze/stall on start up. I was under the impression this was happening because there was residual pressure resisting the piston. Where am I going wrong here?
