This service manual does not include
information on drive mechanism unit and
MAN circuit board.
When servicing, replace the entire drive
mechanism unit or the entire MAN circuit
board if necessary.
For fault judgement, see Chapter 6 simplified
circuit board diagrams that show the voltage
values of major ICs on circuit boards (DRC
and HDM) mounted on drive mechanism unit
and MAN circuit board.

CAUTION-1
CAUTION (COLOR LCD)
LCD display; the liquid crystal display (LCD) panel is mode by highly precise technology.
More than 99.99% of its picture elements (pixels) are effective, but some (less than 0.01%) may appear as colored
bright dots. This mode not indicate a fault as the LCD panel stretches the limits of current technology.
CLASS 1
LASER PROCTECT
CAUTION
This product contains a laser diode of
higher class than 1. To ensure contin-
ued safety, do not remove any covers
or attempt to gain access to the in-
side of the product. Refer all servicing
to qualified personnel.
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.
PRODUCT SAFETY NOTICE
Lithium battery; danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type
recommended by the equipment manufacturer. Discard used batteries according to manufacuturer's instructions.
When replacing the lithium battery it is important to use the same type and connect it correctly.
WARNING:
Lithium batteries contain dangerous chemicals.
Handle and dispose of with great care.
Do not throw in a fire.
Do not short circuit it.
For disposal place in a plastic bag and put in waste bin.

Lead-Free Solder
CAUTION-2
To conserve global environment, lead-free solder is used in this product.
Be sure to read the following before soldering.
Be sure to wear protective goggles so that no solder smoke or scattered solder enters the eye.
Lead-free solder may scatter at high temperatures (600°C).
Caution
Indication of lead-free solder used
"F" is printed on either surface of circuit boards for which
lead-free solder is used.
Characteristics of lead-free solder
The following shows the characteristics of lead-free solder
used in this product:
Composition of alloy (wt%):
Sn-3.0Ag-0.5Cu
Melting temperature:
Approx. 220°C
Solder for servicing
It is recommended that you use lead-free solder
whose characteristics are the same as that used
in product.
It is also possible to service using lead solder. However,
if lead solder is used for servicing, some cautions are
necessary. (Neglecting these cautions could decrease
strength, causing malfunctions.)
Cautions when using lead solder
When replacing components, remove the lead-free
solder previously used for soldered points as far as
possible.
For additional soldering, melt lead-free solder
completely and mix well with lead solder.
[Do not perform repair using the bare soldering iron
tip (without adding solder)].
Soldering iron for servicing
It is recommended that you use a soldering iron
whose temperature at its tip can be set (with
thermal control function).
Lead-free solder melts at a temperature 30° C - 40° C
higher than lead solder. Therefore, workability will
decrease unless you use a soldering iron whose
temperature is high, whose temperature at its tip does not
change greatly (heat capacity is large), and that can be set
to match the work points.
Recommended soldering iron
With thermal control function (temperature setting
range: 320° C - 450° C)
Recommended tip temperatures for
different work points
