I bought a used Wildcat from the yellow classifieds for my new-to-PCPs friend. It came with about 120 bar in it and was holding good for several days. No manual was included. S o my friend finally comes down and we proceeded without the benefit of a manual...Big mistake. First thing, my friend shoots it with no mag inserted(it is easy to dry shoot with the mag in too, if it's indexed on an empty hole) don't like that one bit. So we proceed to fire it half a dozen times before we get a scope mounted, and see that the pressure got down under a hundred bar. so I go fill it off my big bottle and the air just leaks right out. Sounds like it is coming out way in front of where the valve is normally positioned.....maybe where the regulator sits? Anyway, it just sits there and hisses when I try to fill it again. It was holding air when we got it so I think we did something wrong, 1) can dry firing it cause it to leak? Can shooting below 100 bar cause it to leak? 3) how do we fix it?
 
Couldn't the valve get stuck open sometimes when dry firing? I just had to file the sharp edges on the fill port to keep from damaging the fill probe o-rings but luckily I just received spare o-rings yesterday for the fill probe and breech. Also received my dovetail to weaver adapter but I had already installed a weaver rail that would allow my scope to sit lower than the adapter would have.
 
Steeve I will see if I can link the FX part list which is available from the FX site under 'Support" Plus if you do a search for FX Wildcat leaks you should find a post that has a pdf with for troubleshooting leaks for the Wildcat.
