ABSTRACT:
A hand-guided, motor driven working device with at least one working tool, especially a portable power chain saw. The device has a venting device for the fuel tank, with the venting device comprising a flexible tube, which projects from the upper part of the tank chamber. The free end of the tube is closed except for a labyrinth-like passage or opening. The tube is arranged at least partially within a covering or sheathing, and the tube is guided to an essentially dirt- and contamination-free chamber located as far as possible from the tank, the tool, and the motor.
