Service and Inspection Precautions

1. Obey precautionary markings and instructions

Labels and stamps on the cabinet, chassis, and components identify areas
requiring special precautions. Be sure to observe these precautions, as well
as all precautions listed in the operating manual and other associated
documents.

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 0 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.

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.

5. When replacing chip components...

Never reuse components. Also remember that the negati ve 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.
