Zusammenfassung:	A motor-driven chain saw essentially includes a housing having a rear handle and a front handle and a drive unit attached to the housing. A guide bar for accommodating the saw chain for movement thereon is attached to the drive unit. The housing has an extension arm on the underside of the chain saw which extends to the front; the drive unit is seated on this arm and the front handle is attached to the front end of the arm. To increase torsional and bending strength, the extension arm has an S-shaped profile when viewed in cross section. The S-shaped profile has a substantially rectangular configuration and includes lower, middle and upper parts that are parallel to one another and are interconnected by two flanks. The flanks are located in planes that are parallel to the guide bar.
