摘要： A method for the open-loop and closed-loop control of a power tool, in particular a chipping hammer, containing a drive, a control device, a sensor, a transmission and a handle apparatus. The handle apparatus contains a lever element with a signal transmitter and pivotable relative to the sensor. A first and second position of the signal transmitter are sensed by the sensor, wherein the distance between the first and second position corresponds to a first distance. The difference between a maximum distance of the lever element and the first determined distance is determined. A first rotational speed for the drive is set when the determined difference between the maximum distance of the lever element and the first determined distance corresponds at least to a first predetermined threshold value. A second rotational speed for the drive is set after the second position has been reached and after a predetermined period of time has elapsed.

摘要： Handle apparatus on a power tool, in particular a chipping hammer, having a drive, a control device, a transmission device, wherein the handle apparatus contains a lever element that is pivotable relative to a housing of the power tool. The lever element is movable reversibly relative to the housing of the power tool by exertion of a force in one direction, and a sensor device is contained for sensing at least one first or second position of the lever element relative to the housing of the power tool, wherein a first rotational speed value for the drive is settable depending on the first sensed position of the lever element relative to the housing of the power tool or at least one second rotational speed value for the drive is settable depending on the second sensed position of the lever element relative to the housing of the power tool.

摘要： Method for the open-loop and closed-loop control of a power tool, in particular a chipping hammer, having a drive, a control device, a sensor device, a transmission device and a handle apparatus, wherein the handle apparatus contains a lever element with a signal transmitter, said lever element being pivotable relative to the sensor device. The method includes: sensing a first and second position of the signal transmitter by the sensor device; determining an acceleration of the signal transmitter from the first position to the second position by the control device; setting a first rotational speed for the drive by the control device for the output of a first impact energy value of the transmission device when the determined acceleration reaches a first predetermined threshold value or setting a second rotational speed for the drive by the control device for the output of a second impact energy value of the transmission device when the determined acceleration reaches a second predetermined threshold value. A handle apparatus on a power tool, in particular a chipping hammer, is also provided.

摘要： Method for the open-loop and closed-loop control of a power tool, having a drive, a control device, a sensor device, a transmission device and a handle apparatus, wherein the handle apparatus contains a lever element with a signal transmitter, the lever element being pivotable relative to the sensor device. The method involves the method steps of: sensing a first and second position of the signal transmitter; determining a distance covered from the first position to the second position; and setting the drive from a deactivation mode into an activation mode when the distance reaches a first threshold value. A handle apparatus on a power tool is also provided.
