Be alert and use your common sense.

S-3
During work
zFor each procedure, follow the given sequence of steps.
zUse the special tools and instruments, specified for the work in the manual or
commercially available tools and instruments which fit the purpose.
zUse measurement instruments and powered tools which are properly calibrated or
periodically inspected.
zKeep the maintenance area neat and tidy.
zAlways put away parts, materials or tools when not in use.
zWear an eye protector where anything may fly about.
zWhen using sharp objects or cutting tools, make sure that no part of your body lies in
the path of the blade bit, or point.
zBefore finishing your work, make sure that all parts removed during maintenance have
been installed back in their original positions in the machine.
Make sure that no tool or foreign material is left in the machine.

S-4
Prevention of electric shocks
zBefore starting work, make sure that, unless otherwise specifically instructed, there is
no potential electric hazard in the maintenance area such as insufficient grounding or
a wet floor.
zBefore starting work, note where the emergency power-off switches are located and
make sure you know how to operate them.
zUnless otherwise specifically instructed, cut off all power sources to the machine
before starting maintenance. Just switching off the machine power supplies is usually
not enough.
When power is fed from a wall or floor outlet, unplug the power supply cord, or turn off
the switch on the power distribution panel or board. Attach a notice on the panel or
board prohibiting the use of the switch.
If the energy isolating device such as the switch on the power distribution panel or
board accepts a lockout device, turn off the power, lock out the energy isolating
device, and bring the key with you. When you take over the work and the key for the
lockout device if applicable, do not assume that the power is off. Make sure yourself
that the above-mentioned conditions such as switches are satisfied. If necessary,
use a measurement tool to ensure that the power is off.
zDo not touch any uninsulated conductor or surface, where so instructed, which
remains charged for a limited time after the external power supply to the machine is
disconnected.
zWhen working on a machine which has a grounding terminal, make sure that the
terminal is properly connected to the facility’s ground.
zWhen working close to a hazardously energized part, do not work alone; work with
another person who can immediately turn off the power in an emergency.
zDo not wear any metallic item such as a wrist watch with a metallic surface, or metallic
accessories.
If you wear eyeglasses with a metallic frame, take care not to let the frame touch an
uninsulated surface.
zMake sure that your hands and arms are dry.
zUnless otherwise specifically instructed, use only one hand when it is necessary to
work near an exposed live electric circuit.
This prevents the completion of the circuit through your heart even if you accidentally
touch the circuit.
zDo not use a dental mirror near an exposed live electric circuit.
The mirror surface is conductive and can become hazardous even if it is made of
plastic.
zUnless otherwise specifically instructed, do not supply power to any subassembly such
as a power supply unit or a motor while it is removed from the machine.

S-5
Procedures in an emergency
For electric shock
zDo not panic. Do not become another victim through contact with the injured person.
zFirst, shut off the electric current passing through the victim.
Use the emergency power-off switch, if there is one, or, otherwise, a normal power-off
switch. If this cannot be done, push the victim away from the source of the electric
current by using a nonconductive object such as a dry wooden stick.
zThen, call an ambulance.
zIf the victim is unconscious, artificial respiration may be necessary.
A proper method for performing artificial respiration or resuscitation should be learned
beforehand. If the victim’s heart is not beating, cardio-pulmonary resuscitation should
be performed by a trained and qualified person.
For outbreak of fire
zFirst, shut off all the power from the machine using the emergency power-off switch, if
there is one, or the normal power-off switch.
zIf the fire continues burning after the power is shut off, take suitable actions including
the use of a fire extinguisher or a call for the fire department.

CAUTION
zWhen wiring a pulse counter module, be sure to wire it with a shielded
twisted-pair cable and ground the cable by Class D grounding.
zThe shielded twisted-pair cable must be laid at least 30 centimeters away from
noise sources, such as power cables and input/output cables. Never lay it in
parallel with those noise sources, and the length of the cable laid must be
shortest possible.
zIf a counting error occurs in the pulse counter module that has been wired
according to the above rules, lay the shielded twisted-pair cable in a special
duct or conduit, and then ground the duct or conduit.
zAny input terminals that need not be used must be wired as follows:
•If the pulse counter module is used with one-phase pulse input, short the two
input terminals of each of the two pairs of two-phase pulse input terminals;
that is, short A1S and A1C together, then short B1S and B1C together, and
then ground them all together.
•If it is used with two-phase pulse input, short the one-phase pulse input
terminals A2S and A2C together and then ground them together.
•If the stop-signal input terminals STOPS and STOPC need not be used,
short them together and then ground them together.
zA pulse generator may be connected to the pulse counter module by using
either voltage-transistor connection or no-voltage-transistor connection (see
below). Voltage-transistor connection should be used when grounding is
made on the pulse generator side. No-voltage-transistor connection should
be used when grounding is made on the pulse counter module side.
zDo not connect a contact to any pulse input terminal. Disregarding this rule
may result in counting errors due to contact bouncing during closing and
opening of the contact.
