ŸRegularly inspect and maintain your electrical hand

tools	for safe	operational	condition.
Ÿ Do not	use worn	or broken	tools and testers.

ŸNever assume that power has been disconnected from a circuit.checkFirst,that it has been powered-off.

ŸAlways 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.

ŸDo 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.

ŸDo not service the followingth partsthe 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.)

Safety

Inspection

Guide

The

intent of this inspection guide is

to

assist you in identi-

fying

potentially

unsafe

conditions

on these

products.

Each

machine, as it was designed and built, had required

safety items installed to protect

users

and service

per-

sonnel from injury. This guide addresses only those items.

However, good judgment should be

used

to

identify

poten-

tial

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:

ŸElectrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal elec- trical shock).

ŸExplosive hazards, such as a damaged CRT face or bulging capacitor

ŸMechanical hazards, such as loose or missing hard- ware
