(1) Circular saws must not be operated at speeds in excess of that specified by the manufacturer. Speeds must be etched on all new saws. When saws are repaired, remanufactured or retensioned in any way to change their operating speeds, such change of speed must be etched on the saw. These etched speeds must not be exceeded.
(2) Circular saws must be inspected for cracks each time that the teeth are filed or set.
