Hi. I bougth a bobcat mk2 and the regulator pressure are 15-20 bar under cylinder pressure all the time. If i fill the tube to 220 bar the regulator is 200. And when i shot the regulater pressure falls the same as the tube. So if i shot down to 190bar the regulator is 170. I doesent matter how i set the regulator. Anyone who have had the same problem? Its cal.25. Thanks!
