I just recently got this tank in a package deal. When i first filled the tak it was at about 600 psi, I was told it was adjustible but really have no idea how. the seller is no where to be found and seems to be ignoring my plees for help.

fisrt came, filled at 3000 psi out put was 600psi
emptied the tank srewed the valve all the way in filled again now out put is 200-300 psi
so i figured i went the wrong way so i unscrewed it as far as it went without forcing it.
the emptied and refilled again to my horror still outputing 200-300 psi, with this on my xvalve
the gun will not even cock.

Any suggestions would be greatly appreciatred. or even a product name as a starting point
