Abstract
A portable tool, such as a spreader tool, cutting tool or combination spreading/cutting tool is for mobile use. The tool has an electric motor, a rechargeable battery received on the tool, a mechanically or hydraulically driven, displaceable piston rod for performing spreading and/or cutting and/or lifting or pressing. An electronic control and regulation unit controls/regulates the electric motor, such as a brushless DC motor. The electronic control and regulation unit specifies a first operating mode in which the electric motor is operated at a first frequency, and a second operating mode in which the electric motor is operated at a second frequency. The operating mode is switchable by an operator of the tool using a manually operable switch between the first and the second operating modes. The rotational speed of a three-phase current electric motor is higher at the second frequency than at the first frequency.
