Abstract
The invention is directed to a cutting arrangement for a motor-driven chain saw and is configured as a preassembled component which includes a guide bar having a saw chain and sprocket drive wheel. A tensioning device is integrated into the guide bar for holding the parts of the component together. The tensioning device holds the sprocket drive wheel at a spacing from the end face of the guide bar. The tensioning device is adjustable when placing the component on the housing of the chain saw in such a manner that the sprocket drive wheel is released while the saw chain remains under tension. The component can be disassembled into its individual parts by adjusting the tensioning device.
