Abstract
The invention relates to a motor-driven chain saw having a motor mounted in a housing for driving a saw chain on a guide bar. The guide bar extends forwardly in the longitudinal direction of the chain saw from a forward housing end face. The housing is held by a grab handle for holding and guiding the chain saw. The handle has an upper segment projecting over the housing transversely to the longitudinal center axis of the guide bar. The upper segment extends at one end with a transition segment into a lateral segment lying approximately parallel to the plane of the guide bar and next to the housing. The cross section of the upper segment and the cross section of the lateral segment are configured in a shape which departs from the circular shape and are approximately the same. This affords an ergonomically advantageous hold and increases the operational safety. The major cross-sectional axis of the lateral segment lies approximately perpendicularly to the plane of the guide bar and the same cross-sectional axis in the upper segment lies at an angle of less than 90.degree. to a reference plane which extends at right angles in the longitudinal center axis of the guide bar at right angles to the plane of the guide bar.
