Such tools shall not be in lieu of other guarding required by this section, but can only be used to supplement protection provided. - (iv) The following are some of the machines which usually require point of operation guarding: - (A) Guillotine cutters. - (B) Shears. - (C) Alligator shears. - (D) Power presses. - (E) Milling machines. - (F) Power saws. - (G) Jointers. <!-- image -->
