摘要

A hand-held work tool has a housing with a carburetor heater and a grip heater. An internal combustion engine is mounted in the housing and has a crankshaft and an ignition system. The ignition system has a pole wheel with permanent magnets fastened sequentially at a periphery of the pole wheel in the circumferential direction. Charge armatures are mounted in the housing and close the magnetic circuit between neighboring permanent magnets. The charge armatures have legs and excitation coils mounted on the legs. Upon rotation of the pole wheel, the permanent magnets generate an electric current in the excitation coils, wherein a first set of excitation coils is combined to a first partial generator and connected to an electric circuit of the carburetor heater and a second set of the excitation coils is combined to a second partial generator and connected to an electric circuit of the grip heater such that the electric current is supplied respectively to the carburetor heater and the grip heater. The excitation coils of the first set are arranged in a row adjacent to one another in the circumferential direction. The excitation coils of the second set are arranged in a row adjacent to one another in the circumferential direction.
