(1) Jump saws must have guards below the top of the table or roll case. A guard must be placed over the roll casing to prevent persons from walking into or over the saw.

(2) Jump saws, underhung swing saws, or bed trimmers must be arranged so the saws are fully enclosed when not in actual use.

(3) A positive stop must be installed to prevent the saw from passing the front edge of the roll case or table. The throat in the table or roll case must be only wide enough to permit unobstructed operation of the saw.

(4) Guards constructed of not less than two inch wood material or of heavy wire mesh mounted in a steel frame must be placed in front of jump saw trimmers. Stops must be installed to prevent timber from being thrown off the roll case.

(5) Foot treadle operated saws must be provided with safeguards to prevent accidental contact.
