Abstract

The invention is directed to a portable handheld work apparatus such as a motor-driven chain saw. The work apparatus includes a housing having a forward end wall, a rearward end wall defining a plane and a top wall extending between the end walls. A handle is mounted on the top wall for holding and guiding the work apparatus. A work tool is arranged on the forward end wall and a drive motor is mounted in the housing for driving the work tool. A holding lug is provided on the rearward end wall and is pivotable between a rest position wherein the holding lug is recessed in a recess formed in the rearward end wall and an in-use position wherein the holding lug is outside of the recess. The holding lug defines an eyelet through which an operator can pass a rope for holding the work apparatus by attaching the same to a belt or the like thereby freeing the hands of the operator. The holding lug does not constitute a disturbance for the operator when supporting the work apparatus on the body with said rearward end wall.
