Section 45.89. Tenoning machines

(a) Guards. Tenoning machines shall have all cutting heads, saws, if used, and all exposed moving parts carefully guarded. In the case of cutting heads and saws, the guard shall be solid metal.

(b) Single end hand-feed tenoners. Single end hand-feed tenoners shall have a piece of sheet iron placed so that the hands of the operator do not slip off the lever handle into the tool. The guard shall be fastened to the lever.

(c) Double end tenoners. Feed chains and sprockets of all double end tenoning machines shall be completely enclosed, except that portion of chain used for conveying stock. At rear ends of frames, over which the feed conveyors run, sprockets and chains shall be guarded at the sides by plates projecting beyond the periphery of sprockets and ends of lugs. The rear end of the frame, over which the feed conveyors run, shall be extended so that the material may be guided to a point within easy reach of the person removing stock at the rear of the tenoner.

(d) Spoke tenoners. All spoke tenoners shall be adequately guarded to prevent hazard from falling ends of spokes.
