ABSTRACT:
A mechanical drive assembly that is particularly useful for moving a sharpening stone into engagement with a sharpenable chain saw is mounted to the side plate of the chain saw housing. The stone moves linearly a predetermined stroke length toward and away from the chain, and the beginning position thereof is incrementally adjustable, to take into account wear of the stone. The stone may be returned to an original position, for replacement, in another distinct mode of operation.
