Does the Hastan Jet 2 have a pressure bleed screw? I bought a refurb jet 1 and then also the dual cylinders during the NRA 20% off sale. The jet one didn't leak but when I installed the dual cylinders it started losing about 80 bar/day, then more slowly as the pressure decreased. Hatsan wants me to just send it back for repair, but does anyone on the forum know how to bleed the cylinders so I can uninstall/reinstall? Any tips on the install, or guesses on why it's leaking? I mean other than the popular "it's leaking 'cause it's a Hatsan."
