In order to provide a hand-guided machine, which is partially or completely used at low ambient temperatures, with a heating arrangement of the handles, comprising an AC source, an analysis electronic system, at least one temperature sensor connected to the analysis electronic system and at least one electrical heating element supplied with power from the AC source, with which heating of handles of hand-guided machines is possible and which avoids the disadvantages of known handle heaters and particularly relieves the operator in his work activity as well as providing an ergonomically favorable working environment, so that work accidents and occupational illnesses are avoided, it is suggested that the output of the at least one electrical heating element be switched and regulated by an electronic component, controlled by the analysis electronic system, in the form of transistors, IGBTs, GTOs, thyristors, or TRIACs. |
