3.Thread each cam-lock stud into the chuck or faceplate until the depth mark shown in Figure 45 is even with the surface of the chuck or faceplate and the curved indent on the side of the stud faces the locking cap screw hole, as shown in Figure 46. This is an initial adjustment.

6.Insert the chuck onto the spindle, then check the position of each camlock, making sure the cam line points between the "V" marks.

—If one or more of the cams do not point between the "V" marks on the chuck, remove the chuck, and fine tune the camlock stud adjustment by adjusting the stud in or out and using Figure 48 on the following page as a guide to correctly position the cam lines.
