Be careful not to lose screws, washers, or other parts removed.
(3)
Be sure to apply grease to the gears and applicable positions specified in this
chapter.
(4)
When using soldering irons or other heat-generating tools, take care not to
accidentally damage parts such as wires, PCBs, and covers.
(5)
Before handing any PCBs, touch a metal portion of the equipment to discharge any
static electricity charge on your body, or the electronic parts or components may
be damaged.
(6)
When transporting PCBs, be sure to wrap them in the correct protective packaging.
(7)
Be sure to replace self-tapping screws correctly, if removed. Unless otherwise
specified, tighten screws to the following torque values.
TAPTITE, BIND or CUP B
M3 : 7kgf • cm
M4 : 10kgf • cm
TAPTITE, CUP S
M3 : 8kgf • cm
SCREW
M3 : 7kgf • cm
M4 : 8kgf • cm
(8)
When connecting or disconnecting cable connectors, hold the connector bodies,
but not the cables. If the connector has a lock, release the connector lock first to
unlock it.

After a repair, check not only the repaired portion but also all connectors, also
check that other related portions are functioning properly before operational
checks.
