Safety Precautions - Brother ADS-2600W Service Manual

1. SAFETY PRECAUTIONS

To avoid creating secondary problems by mishandling, follow the warnings and precautions
below during maintenance work.
• Be careful not to lose screws, washers, or other parts removed.
• Be sure to apply grease to applicable positions specified in this chapter.
• When using soldering irons or other heat-generating tools, take care not to accidentally
damage parts such as wires, PCBs and covers.
• Static electricity charged in your body may damage electronic parts. When transporting
PCBs, be sure to wrap them in conductive sheets.
• When replacing the PCB and all the other related parts, put on a grounding wrist band and
perform the job on a static mat. Also take care not to touch the conductor sections on the
flat cables or on the wire harnesses.
• After disconnecting flat cables, check that each cable is not damaged at its end or short-
circuited.
• When connecting flat cables, do not insert them at an angle. After insertion, check that the
cables are not at an angle.
• When connecting or disconnecting harnesses, hold the connector body, not the cables. If
the connector is locked, release it first.
• After a repair, check not only the repaired portion but also harness treatment. Also check
that other related portions are functioning properly.
• After assembly, it is recommended to conduct dielectric test and continuity test.
