Abstract: A method for enabling a delivery of a motor-driven processing machine and/or a battery pack for supplying a processing machine with electrical drive power to a delivery point is provided. A transmitting device is arranged on and/or in the processing machine and/or the battery pack. The transmitting device is designed for the wireless transmission of operating and/or status data of the processing machine and/or the battery pack and an identifier. The method includes the steps of: at least identifying the processing machine and/or the battery pack and/or the transmitting device based on the transmitted identifier; and enabling the delivery of the processing machine and/or the battery pack at the delivery point depending on a result of at least the identification.

Abstract: A method provides automated assistance with a recording of a repair of a motor-driven tool. The method a) ascertains at least one component of the tool, at least one assembly group of the tool, and/or at least one component and/or assembly-group type of at least one component and/or at least one assembly group, wherein the component and/or the assembly group have been handled during the repair of the tool, b) determines a number of possible actions carried out during the repair of the tool on the basis of the ascertained component, the ascertained assembly group and/or the ascertained component and/or assembly-group type, and c) outputs the determined number of possible actions.

Abstract: A method determines a presence of a motor-driven tool inside a tool position region and/or a tool position of the tool. A transmitter is mechanically connected to the tool, wherein the transmitter wirelessly transmits a signal. The transmitted signal is attenuated by the tool and has an item of transmitter information for taking the attenuation into account. The method has the steps of: capturing a respective reception signal strength value of the transmitted signal at receivers, wherein the receivers are arranged at different receiver positions; and determining the presence of the tool inside the tool position region and/or the tool position of the tool on the basis of the captured reception signal strength values and the received transmitter information for taking the attenuation into account.

Abstract: The invention relates to an arrangement for identifying a switching position of a switch (on an internal combustion engine in a handheld work apparatus. An energy source for supplying power to an inductive electrical load is provided, it being possible to connect the load to the energy source in order to be switched on and off via a controller. The switch is arranged in a voltage branch which is connected in parallel with the inductive load and in which a zener diode is also connected. The zener diode is activated or inactivated via the switch as a function of the switching position of the switch. The amplitude of the switch-off voltage, which is induced when the inductive load is disconnected, is limited by the zener diode, so that it is possible to read from the magnitude of the amplitude whether the switch is closed or open.

Abstract: The invention relates to a portable handheld work apparatus such as a cutoff machine, motor-driven chain saw, brushcutter, blower apparatus or the like. The apparatus includes a drive motor (2) for driving a work tool (6) and is provided with a security circuit (20). The security circuit (20) switches the drive motor (2) of the work apparatus into an operational-ready state or into an out-of-service state in dependence upon received signals of a receiver unit (18). The receiver unit is configured to receive at least one operating code. The receiver unit (18) is configured for receiving a service code (27) and, with the receipt of a service code, switches the drive motor into only a temporary service state.

Abstract: A hand-held working apparatus has an internal combustion engine having a crankshaft which is driven in rotation. The crankshaft drives at least one tool of the working apparatus via a centrifugal clutch. The working apparatus has a device for determining the speed of the internal combustion engine and a control device which controls the internal combustion engine. It is provided that the profile of the speed of the internal combustion engine is evaluated by the control device, and that the engagement speed of the centrifugal clutch is determined from the profile of the speed of the internal combustion engine. A method of operation is also provided.

Abstract: A handheld work apparatus has a combustion engine with an ignition unit, a unit for supplying fuel and a device to determine the rotational speed (n). The ignition unit includes a spark plug, a coil and a pole group. The pole group and the coil are moved in dependence on the rotational movement of a crankshaft of the combustion engine, whereby a ignition voltage is induced in the coil. The work apparatus has an open loop control which controls the ignition time (ZZP). A diagnostic unit for damage diagnosis is detachably connected to the work apparatus. For damage diagnosis, the diagnostic unit captures the course of the induced ignition voltage over at least one engine cycle when the combustion engine is running and damage is determined on the basis of the course of the captured voltage.
