Abrégé

For manually operated garden shears, it is proposed, in order to cut relatively thick material to be cut, to switch on an additional motor-driven closing force if necessary and to provide an electrical drive motor, which is preferably fed from a rechargeable battery, for this purpose. In order to keep the design of the drive motor and of the rechargeable battery small and to keep the available operating time of the rechargeable battery long, the motor-driven closing force is switched on only in case of need. In particular, the automatic determination of a case of need and the switching-on of the motor-driven closing force by means of an electronic control device in accordance with characteristic variables of the current cutting operation and test criteria stored in the control device are advantageous. In particular, switching-on of the motor-driven closing force can be restricted to cases in which the closing speed of the blade arrangement falls below a second, upper threshold value in the event of a manual force of the user exceeding a first threshold.

For a garden pump that is automatically switched off by means of a flow sensor that detects a minimum flow rate, a delay time between the time at which the flow rate falls below the minimum flow rate and the time at which the drive motor is switched off is set to at least 1.5 minutes, and after the drive motor has been switched off due to the flow rate falling below the minimum flow rate, the drive motor can be switched back on regardless of pressure by means of a control element to be operated by the user. Thus, the control device is made considerably simpler and cheaper compared to known embodiments that automatically switch back on when the pressure falls below a lower pressure threshold, and the loading of the electrical part of the pump is reduced and the service life of said electrical part is increased.
