摘要： A machine tool, such as a hydraulic press, has a movable guard to prevent the operator's hands from being present in the vicinity of the powered operating element, such as a press tool, while the machine is operating. The guard can be actuated automatically or manually by the operator and is connected to a dump valve in the hydraulic system so that power cannot be applied to the operating element at any time except when the guard is fully closed.
