- 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; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages. • 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. 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: 198 Netfinity 6000R Type 8682 Models 1RY, 2RY

Observe the special safety precautions when you work
with very high voltages; these instructions are in the
safety sections of maintenance information.
Use
extreme care when measuring high voltages.
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, non-
grounded 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 con-
ductive; 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.
