Installation
1.UNPLUG THE MACHINE FROM POWER!
2.Mount the back plate on the spindle.
3.Accurately measure the inside of the back relief bore on the chuck. This dimension is critical and should be ± 0.001''.
4.Face the back plate to true it. Make passes across the face until its entire surface has been cut.
5.Turn a shoulder into the face 1⁄8'' deep and 0.001" to 0.002'' larger than the back relief bore diameter. Remember that this is a press fit. Chamfer the corner a small amount to prevent any burrs when installing.
