FX Impact help

i installed a 22 cal barrel on my 25 impact and needed to drop the regulator. Followed the steps in the manual (unscrewed the bottle, fired a shot on min, waited for regulator to vent pressure, turned clockwise).

Now the problem, when I screwed the bottle back on air is coming out of the business end of the barrel and the regulator gauge stays at zero!! I had the bottle at apx 230 bar and when screwed in it’s emptying fast. 

Please let me know what is happening and how to fix it. 

Thanks 
 
I unscrew the reg manometer/gauge to bleed the air from the reg when adjusting the reg down, Ernest said not to fire the gun without the bottle in it. I know AOA said shoot it but i had to shoot it several times to bleed the air from the reg when i tried that and even turning the reg cc wise didn't work for me. Please let us know how you solved the problem

Thanks
 
Never dry fire to bleed reg side doing so valve will not seat properly or will over travel and won’t reset — it won’t happen everytime but if you want to dry fire the safe way IS to tighten down the valve adjusted CW till it’s tight then dry fire this will prevent the valve rod to over travel or just unscew reg adjustment screw 1/8 turn it will dump the reg side. 

If the valve rod isn’t flush with the valve housing do the fallowing; unscrew A20 then A17 pull and push on C1 till valve rod is flush with valve housing. If that don’t work PM me for further trouble shooting.

This won't fix your problem but it will keep you from causing it to happen again someday...

Instead of dry firing your gun to release the air on the regulated side all you had to do is simply loosen the air gauge at the rear of your Impact about 1/4 turn or so and that will let all the air out very quickly. Then simply tighten the air gauge back up and you are done. Never dry fire any pcp without air pressure in the plenum to keep back pressure on the valve pin in order to resist and equalize the force of the hammer strike. (the Daystate electronic firing system may be the exception...).
