making sure the raised key faces outward. Place a KM cutting unit into(see Frame 8). Check for proper operation of the unit by pushing down
the clamping unit. It should drop into the taper easily. If it does not,on the end of the bump-off pin with your finger while tightening and

bump-off pin move in and out as the direction of the torque screw changes.
8. Insert the bump-off pin without its O-ring into the bore, being certain the
angled surface of the bump-off pin will ride on the angled surface of the12. As a final check, rotate the torque screw outward until it stops. Install a
lockrod (see Frame 7).KM cutting unit and tighten the torque screw to the proper torque required
for locking. Ensure that there is no air gap between the locking faces of
the cutting unit and the clamping unit. Loosen the torque screw. Initially,
