Safety Precautions

Warnings and cautions regarding the procedures should be observed to avoid
possible physical hazards and serious accidents that may occur during installation and
servicing.
Labels that describe relevant precautions are attached on the machine.
The instructions on such labels should also be observed during procedures.
1.1

General Precautions

 Power Supply
Unless otherwise instructed in the Service Manual, be sure to turn OFF the power
of the machine and unplug the power plug before servicing. With the power plug
still plugged, you may experience electric shock, burn, or secondary damage due to
short circuit even when the machine is powered OFF. It should be noted, however,
that some servicing procedures, such as voltage measurement, cannot be performed
under power-OFF condition. In such cases, use due care to avoid electric shock, burn,
or secondary damage due to short circuit, as instructed in this manual.
 Drive Mechanism
Be sure to turn OFF the power before servicing the gears, cams, belts, and other drive
mechanism parts. Otherwise, your body or clothing may be entangled.
However, there may be cases where the procedures cannot be performed under
power-OFF condition. In such cases, use due care to avoid entanglement of your
hand, foot, hairs, and clothing with any rotating mechanism, as instructed in this
manual.
 Heavy Objects
Exercise due care regarding your working posture to avoid back pain during removal
and installation of heavy objects.
 Safety Devices
Safety devices (such as fuses, circuit breakers, interlock switches, panels, and covers)
should always be enabled. Never attempt to make any alteration or modification that
may impair their safety features.

 Optical Parts
 When servicing the optical parts with the protective housings removed, be sure to
turn OFF the power switch.
 Never remove the scanning optics unit covers.
 For dust removal procedures, observe the instructions described in the service
manual.
 Some high-voltage parts, such as the photomultiplier, may not be sufficiently
discharged even after power is turned OFF. When servicing such parts, exercise
due care to avoid electric shock hazards (not to touch the connector and terminal
carelessly).
 Before removing the protective housings, be sure to turn OFF the high-voltage
switch (HV switch). If the machine is powered ON with any of the protective
housings removed, the photomultiplier will be damaged.
 Other Working Precautions
 When performing servicing procedures with the protective housings removed
under the powered condition, turn OFF the high-voltage switch (HV switch).
Carefully proceed with the procedures while checking the instructions described
in the service manual, and, when the procedures are completed, put the removed
protective housings back exactly where they were.
 Do not remove or install any part or component while the machine is powered,
because of possible electric shock hazards.
 When performing checks or adjustments under the powered condition, exercise due
care against electric shock or other hazards.
 Do not touch the parts (such as erasure lamps) that remain at high temperature
because you may suffer burns.
 When servicing the scanning optics unit and printed circuit boards, be sure to wear
an antistatic wristband to remove static electricity built on the human body. Static
electricity may cause damage to the printed circuit boards.
 Secure the machine onto the floor in place by use of its adjustable feet or retainers.
 Keep clean the product labels, safety standards labels, product serial number
indications, and so forth attached on the machine, and do not peel them or put
another label over them.
 Before powering ON the machine after completion of the servicing procedures,
make sure that all the parts, screws, connectors, and so forth that were removed
have been reinstalled as appropriate, and that no tool is left in the machine.
 Grounding
Safety provided by grounding is assured by properly establishing power cable and
additional protective ground wire connections and securing the parts with retaining
screws. To maintain safety, ensure that the parts and retaining screws removed for
servicing purposes are restored to states existing upon installation. After the parts and
retaining screws are restored to the above-mentioned states, follow the procedures set
forth in this service manual to verify that the retaining screws are securely tightened to
properly secure the parts.
