ABSTRACT:
A chain tensioner for a chain saw has a cam member in positive engagement with a flange of a plate attached to the guide bar. Rotation of the cam member forces the guide bar away from a drive sprocket of the chain saw to tension the chain. The cam member is clamped in position to maintain the guide bar in the adjusted position. Flats on the cam member in abutment with the flange resist rotation of the cam member when in the adjusted and clamped position. A slot is provided in the cam member to facilitate rotating the cam to force the guide bar away from the drive sprocket.
