Abstract
The invention is based on a hand power tool, in particular a drill hammer and/or a chipping hammer, having a striking mechanism () capable of being driven in a housing () by an electric motor (), via which an insertable tool () situated in a tool mount () is capable of being driven in an impacting manner, and having a sensor unit () via which a characteristic value for a no-load position can be detected. It is proposed that, when a no-load position is detected via a motor control unit (), the electric motor () and, therefore, the striking mechanism () can be actively decelerated.
