Abstract:
A method for setting a gear in a transmission of a power tool, the power tool including an electric motor as well as a controller for setting the rotational speed of the electric motor. A transmission includes an operating device for selecting a gear in the transmission, a shift fork as well as an actuator, the operating device including a signal transmitter as well as a sensor for receiving a signal of the signal transmitter. The method includes: setting the operating device from a first position to a second position for selecting a gear in the transmission; detecting a signal by the at least one sensor according to the second position of the operating device; transmitting a signal to the controller; setting the rotational speed of the electric motor from a first value to a second value by the controller; positioning the operating device from the second position into a third position; detecting a signal by the sensor according to the third position of the operating device; transmitting a signal to the actuator; and setting the shift fork from a first position to a second position with the aid of the actuator for the purpose of changing from a first gear into a second gear.
