– Ensure that another person, familiar with the

power-off controls, is near you.

Attention: Another person must be there to switch

off the power, if necessary.

– Use only one hand when working with powered-on

electrical equipment; keep the other hand in your

pocket or behind your back.

Attention: An electrical shock can occur only when

there is a complete circuit. By observing the above

rule, you may prevent a current from passing through

your body.

– When using testers, set the controls correctly and

use the approved probe leads and accessories for

that tester.

– Stand on suitable rubber mats (obtained locally, if

necessary) to insulate you from grounds such as

metal floor strips and machine frames.

Observe the special safety precautions when you work

with very high voltages; Instructions for these

precautions are in the safety sections of maintenance

information. Use extreme care when measuring high

voltages.

v Regularly inspect and maintain your electrical hand tools

for safe operational condition.

v Do not use worn or broken tools and testers.

v Never assume that power has been disconnected from

a circuit. First, check that it has been powered off.

v 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.

v 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.

v 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.)

v If an electrical accident occurs:

– Use caution; do not become a victim yourself.

– Switch off power.

– Send another person to get medical aid.
