I run a bravo s stitcher with its own stacker. The stacker will eject a bundle when not running but when it is running the forks do not open. I have the settings on what I always run on. The forks move just a bit like they want to open but do not if I stop the machine and hit the eject button it works. What am I missing? This is 96 page book very important little time to do it. Can anybody help?
