I am having problems charging a Air Arms S400.
After putting the female end on and twisting to lock it then turn on the bottle, but nothing going into the cylinder, some air escaping through the hole where the T bar is, nothing registers on the gauge on the dive bottle, gun has just under 100 reading. Dive bottle is not empty, just put 200 in my other gun, no problems.
More than likely something I am doing wrong, this is the first AA i have tried to fill.
Please somebody tell me what I am doing wrong !! gun is only a day old.
