SECTION 1
DISASSEMBLY
1.1 BEFORE ASSEMBLY AND DISASSEMBLY
1.1.1 Precautions
1.Be sure to remove the power supply unit prior to mount- ing and soldering of parts.
2.When removing a component part that needs to discon- nect the connector and to remove the screw for remov- ing itself, first disconnect the connecting wire from the connector and then remove the screw beforehand.
3.When connecting and disconnecting the connectors, be careful not to damage the wire.
4.Carefully remove and handle the part to which some spacer or shield is attached for reinforcement or insula- tion.
5.When replacing chip parts (especially IC parts), desolder completely first (to prevent peeling of the pattern).
6.Tighten screws properly during the procedures. Unless specified otherwise, tighten screws at a torque of 0.088N•m(0.9kgf•cm).
