1. A hydraulic tool comprising:
a working head, the working head comprising head indicia that identify a type of the working head;
a tool frame having a piston;
a hydraulic system coupled to the piston;
a coupling mechanism, the coupling mechanism releasably coupling the working head to the frame and coupling the piston to a working surface of the working head;
a head sensor, the head sensor being adapted to detect the head indicia; and
a controller connected with the head sensor and the hydraulic system,
wherein the controller receives a signal generated by the head sensor in response to the detected head indicia, determines the type of the working head, determines a maximum force to apply to the working surface based at least in part on the determined working head type, and controls the hydraulic system to apply the maximum force.
