Beschreibung
Zusammenfassung:	A handheld work apparatus has a drive motor which drives a work tool and a generator. The work apparatus has a first electrical load and a connectable second electrical load. The generator provides the electrical power for the simultaneous operation of the two loads. The work apparatus has a control unit for controlling the power supplied to the first electrical load. In order to supply approximately the same power independent of voltage fluctuations, a voltage monitoring circuit is provided which, in a first operating state, sets a first signal sequence for operating the first load and, in a second operating state, sets a different second signal sequence for operating the first load. The mean power of the first signal sequence and that of the other second signal sequence are approximately equal.
