Abstract
A method for operating a hydraulically actuated work tool having a work jaw is provided. Once an increase in force applied as a result of a hydraulic pressure has been reached, the work process does not require any further force or a maximum permissible hydraulic pressure has been reached. The hydraulic pressure is applied by a pump piston that travels through a pump path and a return path in each pump cycle. The hydraulic pressure is recorded over a time for a change from a pressure increase range to a pressure-maintaining range corresponding substantially to a specific pressure value from the pump path into the return path. At the end of a pump cycle, if the reached pressure-maintaining range exceeds a predefined pressure-maintaining range, an indication is concluded that the tool needs to be checked for a break in the work jaw.
