Abstract
A device for controlling the speed of an internal combustion engine in a working tool including a device for recognizing a special operating state of the working tool. By way of example, a special operating state can be taken to mean the start-up of the internal combustion engine or a danger that can occur when the user lets go of said working tool or the tool tips over. An adjustment device adjusts the engine speed of the internal combustion engine to a safety speed that is below the operating speed of the internal combustion engine when the special operating state is recognized.
