Setting screw holder stripped on Altaros

I was charging my tank with the Altaros and the screw on left of box, that controls total amount of pressure going into tank, Jumped out about 3/8" and stopped. I tried to screw it back in but the black piece of plastic that holds the screw is stripped. There is a piece behind it that is made of brass . It has a hole in it that the part . The part that goes into the brass piece has a teat on the end that goes into the brass part. The brass plug with hole in it is screwed in first and the part with teat and spring goes in next. and then the plastic plug that has been drilled and tapped for 6x32 npt screw goes into center of plug. My screw actually shot out of that drilled and tapped hole and it stripped . Not I cant screw in the screw. and lower amount of air pressure going to bottle.[url="https://s19.postimg.org/jt8jhinhf/DSC_0238_1024x685.jpg"][img]https://s19.postimg.org/jt8jhinhf/DSC_0238_1024x685.jpg[/img][/url] Couldn't I buy a plug mad of metal and drill and tap a hole in center to hold screw. So I could adjust the out flow of altaros total out put air pressure? I am getting very nervous about when I will get my altaros ready for my new daystate Regal XL. I don't think there is anything wrong with the Altsros except maybe a fitting loose, leaking air. I don't think I am setting the out flow from altaros to tank properly. I don't know whether to choke it down or open it up. When ever something new comes on the market I usually jump on it. I there isn't enough being written about that item. You can find lots on the showbox but not much on the Altaros..If Altaros would put a schematic of all the parts with name of parts and how they are placed on the compressor, it would be easier to order new parts of tell what parts you think you are having trouble with. I talk to Altaros last week and they said a distributor in US may start selling the Altaros in the US. I wish they would hurry and start selling is we would have a company we could get parts from in a short time.
