Hello
My brother has just bought the above air rifle and we are having problems charging the cylinder.
We were using it to get the scope set up today and once the pressure got to say between 100 and 75 bar, a hissing noise started and after around 5 minutes, the cyclinder was empty.
When trying to charge it up using a high pressure hand pump, air is coming straight through and out of the barrel, everything is set up on the gun as it should for charging.
Can anyone help or know of any fixes?
