Many electrical and mechanical parts have special safety-related characteristics. These are often not evident from visual
inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for a
higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this
Service Manual. Electrical components having such features are identified by marking with a
on the schematics and
the parts list in this Service Manual. The use of a substitute replacement component which does not have the same
safety characteristics as the HITACHI recommended replacement one, shown in the parts list in this Service Manual, may
create shock, fire, or other hazards. Product safety is continuously under review and new instructions are issued from
time to time. For the latest information, always consult the current HITACHI Service Manual. A subscription to, or
additional copies for, HITACHI Service Manual may be obtained at a nominal charge from HITACHI SALES
CORPORATION.

CONTENTS/CAUTION
Notes When Using Service Manual
The following shows the contents to be noted when using service manual:
1. Value units used in parts list
This table shows locations of each part on circuit board
diagrams. The locations are indicated using the guide
scales on the external lines of diagrams.
1) One diagram indicated for each board
The values, dielectric strength (power capacitance) and
tolerances of the resistors (excluding variable resistors)
and capacitors are indicated in the schematic diagrams
using abbreviations.
[Resistors]
Certain symbols are indicated below for value units of
resistors, capacitors and coils in parts list. When you
read them note the following regular indications:
