Abstract

A power saw system has a power saw with housing; guide bar; and saw chain driven about the guide bar by an electric drive motor. A battery is arranged outside of the housing. A power cable is connected with its first end through an electrical connection to the battery and with the second end to the drive motor to supply the drive motor with power. An elastic securing element is connected by a fastening element to the housing. A connecting device connects by a mechanical connection the securing element to an operator of the power saw. The connecting device has an overload protection separating the mechanical connection between securing element and operator when a maximum pulling force is surpassed. Securing element and power cable form a cable assembly. A pull-out force for separating the electrical connection is smaller than the maximum pulling force.
