Abstract
A control method for a percussive hand-held power tool () includes the steps: detecting a switching state of an operating button (), detecting a temperature T using a temperature sensor (), activating an electropneumatic striking mechanism () in response to an actuation of the operating button (), an exciter () of the electropneumatic striking mechanism () being moved forward and backward along a working axis () at a repetition rate R, whereby a striker () coupled to the exciter () via a pneumatic chamber () is also moved. If the temperature T is greater than a limiting temperature Tc, the repetition rate R is continuously increased from idle up to a setpoint value (). A duration until reaching the setpoint value () is less than 10 cycles. If the temperature T is less than the limiting temperature Tc, a duration until reaching the setpoint value () is greater than 200 cycles.
