Abstract
A power tool includes: a drive unit for a tool; an operating device for activating the power tool; a measuring device for measuring a motion of the power tool; and a filter for filtering at least one measured value of the measured motion. The operating device is configured to reduce a power output of the drive unit when the filtered, measured value corresponds to a state of reduced ease of operation.
Claims15
A power tool, comprising:
- a tool unit;
- a drive unit for the tool unit;
- an operating device for activating the power tool;
- a measuring device for measuring a motion of the power tool;
- at least one filter for filtering at least one measured value of the measured motion;
- and
- a control unit configured to at least one of reduce a power output of the drive unit and decelerate the drive unit, when the filtered value of the measured motion reaches a specified comparison value.

A method for operating a power tool having a drive unit for a tool, comprising:
- measuring a motion of the power tool using at least one measuring signal;
- filtering the at least one measuring signal;
- and
- at least one of (i) reducing a power output of the drive unit and (ii) decelerating the drive unit, when the filtered measuring signal reaches a limiting value which corresponds to a reduction in an ease of operation.
