Abstract
A hand-held power tool has a lower mass and an upper mass. The lower mass has a tool and a working device for causing the tool to effect a work movement. The upper mass is movable relative to the lower mass and has a drive motor for the working device. A first vibration decoupling device is arranged between the lower mass and the upper mass for decoupling the upper mass from the lower mass in terms of vibration. A guide drawbar guides is provided for guiding the work tool by an operator. An electrical energy storage provides electrical energy for starting the drive motor. A drawbar carrier is carried by the upper mass and is connected to the upper mass via a second vibration decoupling device. The guide drawbar is attached to the drawbar carrier, and the energy storage is carried by the drawbar carrier.
