Abstract (en)

[origin: EP1055489A2] The determination method is carried out, so that during the individual, timely successive operational sections of the hydrau impact set, signals are produced. The number of which is proportional to the strokes carried out by the percussion pistons in a movement direction. The number of signals is continuously totalled up and is stored as a total figure. The respective actual tot number of the signals is made identifiable at least intermittently in the form of an indication concerning the application condition.
