Abstract

The present invention relates to a method for controlling a power tool comprising a housing, an electric motor, a tool holder for supporting a tool bit and a conversion mechanism for converting the rotational movement of the output shaft of the motor into a reciprocating movement of the tool bit when being supporting in the tool holder, wherein oscillations of an element of the power tool are detected, wherein a quantity characterizing the oscillations is monitored and wherein the rotational speed of the electric motor is controlled such that the quantity does not exceed a preset value.
