(a)
Miscellaneous operations.
Circular table saws used for
				  rabbetting, plowing, grooving and dado operations exclusively shall not be
				  required to have spreaders attached. All saws used for these operations, except
				  the self-feed variety, shall be guarded by hoods in accordance with §
										45.125 (relating to circular
				  crosscut saws). Guards supported from the top or side shall be accepted on saws
				  of this character.
(b)
Combination saws.
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.
Tilting table saws shall be guarded in accordance with §
										45.125 or §
										45.126, except that guards
				  supported from the top and side shall be accepted on ripsaws used occasionally
				  for rabbetting, plowing, grooving, or dado operations. Nothing in this
				  subsection shall be construed to permit the omission of the spreader, except
				  when actually performing rabbetting, plowing, grooving or dado operations. On
				  completion of such operations, the spreader shall be immediately replaced.
				  Tilting table combination laws shall be guarded in accordance with subsection
				  (b).
(d)
Cutoff
				  saws.
Traveling cutoff table saws shall have the hood supported from
				  the saw carriage. Single cutoff table saws and double or multiple cutoff table
				  saws in fixed position shall be guarded in accordance with §
										45.125. Hoods supported from the
				  top shall be accepted. 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.
