IBM 3270 Maintenance Manual page 6

• Lift the equipment or parts by standing or
pushing up with your leg muscles; this action
removes the strain from the muscles in your
back. Do not lift any equipment or parts that
are too heavy for you.
The maximum load to be lifted is that which,
in your opinion and management's, does not
jeopardize your own health or well-being, or
that of other employees.
• Put removed machine covers in a safe place
while you are servicing the machine.
Reinstall the covers before returning the
machine to normal operations.
• Always keep tools, tool kits and other service
items away from walk areas so that other
persons cannot trip over it. For example,
keep the kit under a desk or table.
• Observe good housekeeping practices in the
area of the machines while you are
performing maintenance and after completing
it.
• After maintenance, reinstall all safety
devices, such as guards, shields, labels, and
ground wires. Exchange safety devices that
are worn or defective. (Remember: the safety
devices protect you from a hazard. You
destroy their purpose if you do not reinstall
them when you have completed the servicing.)
