Abstract

A power tool has a drive unit and an operating handle. At least one electrical line connects the operating handle and the drive unit to each other. The at least one electrical line is fastened at a first electrical connection location to the operating handle and at a second electrical connection location to the drive unit. A safety cable extends along the at least one electrical line between operating handle and drive unit. The safety cable has a first end section and a second end section. The first end section is connected mechanically fixed at a first fixation location to the operating handle. The second end section is connected mechanically fixed at a second fixation location to the drive unit. The at least one electrical line and the safety cable are guided together such that the safety cable forms a tear-off protection for the at least one electrical line.
