I used to repair this type of equipment, and the potential for endangerment of life and limb are being understated. . this press gets it power from the potential energy stored in a spinning flywheel. once cycled nothing will stop this type of press except the knife pulling out the dog, or hitting something harder the the punch tonnage + 20~30%.
the second condition will either shear off the dog (you hope) or break the shaft (you hope not. I saw this happen, the flywheel went through two buildings and sereral cars before ending up spinning like a quarter half a block away).
