•The three self-centering jaws are reversible to allow the holding of larger workpieces. jaws installed in order 1, 2, and 3 to match the numbers on the housing. To fit them reversed, insert them in the order 3,2,1. Fit the slider plate into the housing and place the Circlips over the shaft to secure it. Turn the slider over so that the front end of the slider is about to pop into one of the slots. Feed into Jaw 1, large end first, and rotate the slider plate to snap it. Repeat with Jaw 2 in the next hole, then Jaw 3 in the next hole.
