Abstract
A method for automatically cycling a torque wrench. The method includes providing a hydraulic torque wrench. Providing an actuating device on the hydraulic torque wrench. Providing a switching device on the hydraulic torque wrench. Adapting the switching device to be activated by the actuating device when a piston of the torque wrench is at the end of a stroke. The embodiments of the method allow a user to ensure that a proper torque on a threaded fastener is achieved. This ensures that the pressure achieved within the system is a result of a proper torque applied to a threaded fastener being achieved, and not a result of the piston at the end of its stroke.
