Combination rip and crosscut table saws (revolving double arbor saws) shall be fully guarded in accordance with § 45.125 or § 45.126 (relating to circular crosscut saws; and circular ripsaws), except that a guard supported from the top or side shall be accepted. Nothing in this provision shall be construed to permit the operation of the ripsaw without a spreader, except when actually performing rabbetting, plowing, grooving, or dado operations. On completion of such operations, the spreader shall be immediately replaced. Single disk combination rip and crosscut saws shall be guarded in accordance with § 45.126.(c)Tilting table saws.

Traveling double or multiple cutoff table saws shall have the hood supported from the saw carriages. Both single and double or multiple cutoff table saws shall not be required to have automatic hoods, if carriage feed or some adaption of the carriage feed principle is used, if each saw is equipped with a hood, secured to the carriage, which completely covers the saw when not in use and when the carriage is in the loading position, or if the entire machine is fenced in at back and sides to a height level with the tops of the saws. Form feed shall be construed as an adaption of the carriage feed principle.(e)Swing cutoff saws. Swing cutoff saws shall be provided with the following devices: (1) Each swing cutoff saw shall be provided with an approved rigid metal hood arranged so that the part of the saw above the table shall be covered down to a plane level with the lowest edge of the collar. This hood shall be constructed so as to afford the operator a view of the cutting edge of the saw at the point of contact with the stock. The hood shall be designed so as to protect the operator from flying splinters and broken saw teeth.(2) Each swing cutoff saw shall be provided with an effective device to return the saw automatically to the back of the table when released at any point of its travel. The device shall not depend for its proper functioning upon any rope, cord or spring.(3) Each swing cutoff saw shall be provided with limit chains or other positive stops to prevent the saw from swinging beyond the front and back edges of the table.(4) A latch may be provided to catch and retain the saw at the rear of the table, but nothing in this subsection shall be construed to render the latch the sole means of retaining the saw at the rear of the table.(f)Inverted swing cutoff saws. Inverted swing cutoff saw or jump saw shall be guarded by an approved fixed hood, extending over the complete line of travel of the saw, not more than three inches above the top of the largest saw used on the machine. The hood shall be supported at the rear. In lieu of a hood, an automatic guard secured to the frame or arbor and operated by the travel of the saw shall be accepted.(g)Rear and under guarding. The portion of all circular saws which is beneath and behind the saw table shall be effectively guarded by the exhaust hood or some other device. This section cited in 34 Pa.
