ABSTRACT:
An improved device for controlling a working machine of the type having a chuck body including a rotary chuck cylinder closed by a cylinder cover to define a substantially closed pressure space and a chuck piston slidably disposed in the pressure space for displacement responsive to a fluid pressure, includes, a pulse generator member axially guided within the chuck body in communication with the pressure space for movement responsive to one of the fluid pressure at a predetermined level and the position of the chuck piston at a predetermined position, or both. A switch is provided outside of the chuck body at a spaced location therefrom for switching the machine off. A control member is displaceably mounted in the chuck body operative to interconnect the pulse generator member responsive to movement of the pulse generator member.
