CHAPTER III DISASSEMBLY AND REASSEMBLY
3.1 SAFETY PRECAUTIONS
(1) The disassembly or reassembly work should be carried on a grounded antistatic
sheet. Otherwise, the LSIs and electronic parts may be damaged due to the
electricity charged in your body.
(2) When transporting PCBs, be sure to wrap them in conductive sheets such as
aluminum foil.
(3) When using soldering irons and other heat-generating tools, take care not to
damage the resin parts such as wires, PCBs, and covers.
(4) Be careful not to lose small parts such as screws, washers, or other parts
removed for parts replacement.
(5) Tighten screws according to the torque listed below.
(6) Lubricate according to the lubrication points list.
