I am trying to work out the quirks in one of my 320G presses and the thing that is bothering me the most is that the grippers are closing when the cylinder reaches the feed board. The gripper pedal won’t open them at this point. The gripper bar stops at the proper vertical orientation, but I think it may be closer to the edge of the feed board than it is meant to be. Should I assume that the cylinder is meshed one tooth off and needs to be rolled off the end, reset, and the bumper springs readjusted to make it stop vertical further to the right? The other press isn’t much help because the cylinder is even further out of its proper meshed position. It should be a bit of a chore to roll these off the end of the bed.
