Abstract
A radial arm saw guard with operational interlock and adjustable outfeed user barrier is disclosed. The radial saw includes a motor driven saw blade that is mounted on a yoke depending from a supporting arm that overhangs a worktable. The motor driven saw blade is movable relative to a worktable mounted fence in order to enable the motor driven saw blade to be operated for rip cutting of workpieces longitudinally relative to the fence and for cross cutting transverse relative to the fence. A blade guard is mounted in fixed position relative to the yoke for covering at least approximately an upper half of the motor driven saw blade. An adjustable outfeed user barrier is mounted to the upper blade guard for operation between an upper disengaged position exposing the motor driven saw blade and a lower engaged position covering an outfeed end of the motor driven saw blade to protect a user during rip cutting. An interlock prevents rip cutting by the motor driven saw blade unless the adjustable outfeed user barrier is in its lower engaged position. The adjustable outfeed user barrier, in addition to being adjustable for workpieces of different thickness, is also adjustable for accommodating motor driven saw blades of different diameter.
