  • Patent number: 10800065
    Abstract: A hand-guided power tool has an internal combustion engine that is arranged in a power tool housing and drives a tool member of the power tool. A fuel tank and at least one electric component are provided. A control device that is an electronic control unit is connected to the at least one electric component and controls the at least one electric component. The power tool has a top face which, when parking the power tool in a usual parking position on a flat horizontal support surface, is facing upwardly. The electronic control unit has a plug contact and a connecting plug is plugged into the plug contact. The connecting plug is connected by a connecting line to the at least one electric component. The connecting plug is arranged on a top side of the control device which is facing upwardly in the usual parking position of the power tool.
