(4) Welding or slotting of cracked saws must be done by a sawsmith under a procedure recommended by the saw manufacturer. Holes must not be drilled in saws as a means of arresting cracks. After saws are repaired they must be retensioned. Unless a sawsmith is employed, saws must be returned to the manufacturer for welding or tensioning.
