Okey dokey, tried the above with my Andreani SP2 for the first time, on vacuum cycle damper rod and ifp withdrew into damper body and rezi respectivily, however, on the pressure cycle the ifp stayed at the bottom of the rezi and did not move, machine was attached to the bleed port at the bottom of the damper body by the way. I then tried the old fashioned syringe into the bleed port in the ifp and after a few cycles the bleed was perfect. Is it safe to connect the machine in the same manner ? Anything I was doing wrong ? I'm still on a journey of discovery so dont shoot me down in flames ! Thanks Richie.
