Abstract
A chain tension arrangement of a chain saw having a freely displaceable pin (19) in the saw body introduced into suitable hole (21) in the sword (15) and a tension screw (24) in the cover (10) which covers the centrifugal clutch and is included into the attachment of the sword. For the chain tension moment no presetting of the chain tightening arrangement is required. Owing to the shape of the parts those ones get engaged with each other when fitting the cover. Then the chain tightening is effected with a set screw (25) in the cover by means of a simple hand grip and, after that, the sword attachment is tightened.
