CAUTION.
Avoid cross threading the screws that attach the rear case to the front
case. An easy way to avoid this is to slip the screw into the hole and, using slight
pressure, slowly rotate the screw counterclockwise until you feel the screw slip
into the screw threads. Then tighten the screw clockwise. A properly started
screw will have very little resistance going in.
