ABSTRACT:
In a circular power saw blade mounting arrangement of the kickback clutch type, the blade clamping washer, spring washer and blade screw are retained as a permanent subassembly to eliminate the possibility of substituting an incorrect part. Markings on the exposed face of the clamping washer and the spring washer provide visual indication as to whether the spring washer is properly tensioned.
