A blade guard and lifter therefor surround the saw blade, interlocking when raised by a workpiece as a result of relative movement caused by a secondary linkage. Two pair of primary linkages pivotally connect the blade guard to the splitter. The dual secondary linkage pivotally attaches the parallel plates of the lifter to one of the two pivot points of the primary linkages. Any lifting force is resisted by the rigidity of the primary link that does not share a pivot point with the secondary linkage. A dust collector can be provided to the table saw to minimize respiratory hazards.
