Abstract

In a method for operating a power tool with a diagnostic device, wherein the power tool has an internal combustion engine, a generator as an energy supply, and an electronic control unit, wherein a diagnostic device is connectable to the electronic control unit, and wherein the electronic control unit has an operating mode and a diagnostic mode, a non-uniform voltage signal is supplied by the generator as an energy supply and a uniform voltage signal is supplied by the diagnostic device as an energy supply. The electronic control unit evaluates the voltage signal that is being supplied as an energy supply and switches to diagnostic mode when the voltage signal is the uniform voltage signal supplied by the diagnostic device.
