Safety Procedures
Safety cannot be overemphasized. To ensure personal
safety and the safety ofco-workers, each CE should make it
an everyday practice to'observe safety precautions at all
times. All CEs should be familiar with the general safety
practices and procedures for performing artificial respira-
tion that are outlined in
CE
Safety Practices,
S229-1264.
For convenience, the
-1
printing of this form has been
reproduced.
Always use a reliable voltmeter to verify that power is
actually off after using power-off switches. Although all
power supplies are provided with bleeder resistors to drain
off capacitor charges when power is dropped, it is wise to
check all capacitors with a meter before attempting
maintenance. A defective bleeder resistor could create an
unexpected hazard.
Anyone working near elect~icalcircuits may accidentally
come in contact with live voltage.
Round off sharp edges on plastic guides; replace broken
guides.
Check that all applicable safety devices are on the
machine.
Check all safety devices for proper operation.
Do not permit machines to be run unattended with covers
open or removed.
Leave the escapement gearing cover in place at all times
when the machine is running.
Turn off power when tilting the base.
Use only IBM approved products. Read the labels. As a
general rule, cleaning fluids should be used only in an open
area. Breathing the concentrated vapors, even for a short
time, may cause immediate reactions.
Review Customer Engineering Memorandums (CEMs) for
current safety practices.
