Abstract
A mobile portable tool, such as a spreading device, cutting device or combined device with cutting and spreading function includes a housing. An electric motor is located in the housing. The tool includes a rechargeable battery or a connection to an external electrical energy source. The tool is a mechanically or hydraulically driven and has a displaceable piston rod spreading and/or cutting and/or lifting and/or pressing work. An electronic open-loop and closed-loop control unit controls the electric motor and includes a printed circuit board and control cables with a connector for transporting control signals. For under water operation while still having a simple design, the electric motor is a brushless direct-current motor. The electronic components of the printed circuit board are enclosed by a potting compound to prevent water entering, and the connector of the control cable is protected against the ingress of water.
