Abstract
A control method is provided for a hand-held power tool (1), which includes a motor (5) for rotationally driving a tool holder (2) about a working axis (12), including the following steps: detecting a rotary motion of the hand-held power tool (1) about the working axis (12); detecting a rotary or pivoting motion about a transverse axis (18) extending transversely to the working axis (12); triggering a safety function for reducing the torque output of the motor (5) when the rotary motion about the working axis (12) exceeds a limiting value, and suppressing the safety function when the rotary or pivoting motion about the transverse axis (18) is greater than a threshold value.
