Abstract

A breaker machine includes a power source, a tool holder arranged to receive a tool and a power driven striking mechanism arranged to strike a tip of the tool with a striking frequency on a hard surface. The breaker machine further includes control circuitry arranged to control an output from the power source and load detection means arranged to detect the load of the power source and transmit information relating to the detected load of the power source to the control circuitry. The control circuitry is arranged to receive information relating to a load of the power source, select a striking frequency based on the information relating to the load of the power source and to apply the selected striking frequency by ramping a current striking frequency to the selected striking frequency based on a predetermined ramping scheme by controlling the output from the power source.
