4. Inspect after completing service
After servicing, inspect to make sure that all screws, components, and wiring have been returned to their original condition.
Also check the area around the repair location to ensure that
repair work has caused no damage, and confirm safety.
2. Use designated parts only
The set’s components possess important safety characteristics,
such as noncombustibility and the ability to tolerate large
voltages. Be sure that replacement parts possess the same safety
characteristics as the originals. Also remember that the ( mark,
which appears in circuit diagrams and parts lists, denotes components that have particularly important safety functions; be extra
sure to use only the designated components.
3. Always follow the original design
when mounting parts and routing wires
The original layout includes various safety features, such as inclusion of insulating materials (tubes and tape) and the mounting of parts above the printer board. In addition, internal wiring
has been routed and clamped so as to keep it away from hot or
high-voltage parts. When mounting parts or routing wires. therefore, be sure to duplicate the original layout.
5. When replacing chip components...
Never reuse components. Also remember that the negative side
of tantalum capacitors is easily damaged by heat.
6. When handling flexible print boards...
• The temperature of the soldering-iron tip should be about 270C.
• Do not apply the tip more than three times to the same pattern.
• Handle patterns with care; never apply force.
Caution: Remember that hard disk drives are easily damaged
by vibration. Always handle with care.
