Abstract
The invention is directed to a motor-driven chain saw having a drive motor arranged in a housing. The drive motor drives a saw chain on a guide bar via a sprocket wheel. The guide bar extends forwardly in the longitudinal direction of the chain saw and has an elongated slot in its rearward end facing toward the housing. Stud bolts fixed on the housing extend through the elongated slot in a direction transverse to the longitudinal direction of the chain saw. The rearward end of the guide bar is clamped between the housing and a sprocket-wheel cover through which the stud bolts extend. A holding device separate from the sprocket-wheel cover is provided at the rearward end of the guide bar for holding the rearward end of the guide bar in its position on the housing when the sprocket-wheel cover is removed. This holding device reliably holds the guide bar for mounting the saw chain.
