2.2 DISASSEMBLY AND REASSEMBLY
Precautions on Safety
(1) Disassemble and reassemble the machine on a grounded antistatic sheet.
Touching electronic components such as an LSI with an electrified hand will
break them, as they are easily affected by static electricity.
(2) Wrap the machine in an electrically conductive aluminum sheet before carrying
it.
(3) When using heating tools such as soldering iron, take care not to thermally
break resin components such as a wire, a PCB, and a cover.
(4) Take care not to lose small components, such as a screw and a washer, which
have been removed to replace other components.
(5) Tighten screws according to the list of tightening torque below.
