The mechanism, when actuated, shall cause pliers to rotate about its longitudinal axis in intended direction(s). Each hilt actuation of the mechanism shall cause the pliers to make the following minimum nwnber of coniplete T0t2 bons:
(a) for 6 in. (152 mm) size, 24 rotations (with automatic return, 2 mtations)
(b) for 9 in. (229 mm) size, 3 rotations (with automatic return, 2’ rotations)
(c) for 12 in. (305 rr.m) size 4 rota tions (with automatic return. rotations) (‘Type 1)(Rversible, 3 rotations)
The design of th mechanism shall permit a comfortab)e, adequate grip by the operator.
