Regularly inspect and maintain your electrical hand tools for safe operational condition. Do not use worn or broken tools and testers. Never assume that power has been disconnected from a circuit. First, check that it has been powered-off. Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds. Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage. Do not service the following parts with the power on when they are removed from their normal operating places in a machine: - Power supply units - Pumps - Blowers and fans - Motor generators and similar units. (This practice ensures correct grounding of the units.) If an electrical accident occurs: - Use caution; do not become a victim yourself. - Switch off power. - Send another person to get medical aid.

Regularly inspect and maintain your electrical hand

tools for safe operational condition.

Do not use worn or broken tools and testers.

Never assume

that power has been disconnected

from a circuit.

First,

check

that it has been

powered-off.

Always look carefully for possible hazards in your

work area.

Examples of these hazards are moist

floors, nongrounded power extension cables, power

surges, and missing safety grounds.

Do not touch live electrical circuits with the reflective

surface of a plastic dental mirror.

The surface is

conductive; such touching can cause personal injury

and machine damage.

Do not service the following parts

with the power on

when they are removed from their normal operating

places in a machine:

–

Power supply units

–

Pumps

–

Blowers and fans

–

Motor generators

and similar units.

(This practice ensures correct

grounding of the units.)

If an electrical accident occurs:

–

Use caution; do not become a victim

yourself.

–

Switch off power.

–

Send another person to get medical aid.

Asset ID allows the computer to be scanned by

various radio frequency emitting devices supplied by

independent companies.

Asset ID is intended for use

only with radio frequency equipment that meets

ANSI/IEEE C95.1 1992 RF Radiation Limits.

Safety Inspection Guide

The intent of this inspection guide is to assist you in

identifying potentially unsafe conditions on these products.

Each machine, as it was designed and built, had required

safety items installed to protect users and service

personnel from injury.

This guide addresses only those

items.

However, good judgment should be used to identify

potential safety hazards due to attachment of non-IBM

features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine

how serious the apparent hazard could be and whether

you can continue without first correcting the problem.

Consider these conditions and the safety hazards they

present:

Electrical hazards, especially primary power (primary

voltage on the frame can cause serious or fatal

electrical shock).
