							Safety information
The following section presents the safety information that
you need to be familiar with before servicing an IBM
mobile computer.
General safety
Follow these rules to ensure general safety:
vObserve good housekeeping in the area of the
machines during and after maintenance.
vWhen lifting any heavy object:
1. Ensure you can stand safely without slipping.
2. Distribute the weight of the object equally between
your feet.
3. Use a slow lifting force. Never move suddenly or
twist when you attempt to lift.
4. Lift by standing or by pushing up with your leg
muscles; this action removes the strain from the
muscles in your back.Do not attempt to lift any
object that weighs more than 16 kg (35 lb) or objects
that you think are too heavy for you.
vDo not perform any action that causes hazards to the
customer, or that makes the equipment unsafe.
vBefore you start the machine, ensure that other service
representatives and the customer’s personnel are not in
a hazardous position.
vPlace removed covers and other parts in a safe place,
away from all personnel, while you are servicing the
machine.
vKeep your toolcase away from walk areas so that other
people will not trip over it.
vDo not wear loose clothing that can be trapped in the
moving parts of a machine. Make sure that your sleeves
are fastened or rolled up above your elbows. If your hair
is long, fasten it.
vInsert the ends of your necktie or scarf inside clothing or
fasten it with a nonconductive clip, approximately 8
centimeters (3 inches) from the end.
vDo not wear jewelry, chains, metal-frame eyeglasses, or
metal fasteners for your clothing.
Attention:Metal objects are good electrical
conductors.
vWear safety glasses when you are hammering, drilling,
soldering, cutting wire, attaching springs, using solvents,
or working in any other conditions that might be
hazardous to your eyes.
Safety information
Introduction13 
						

							vAfter service, reinstall all safety shields, guards, labels,
and ground wires. Replace any safety device that is
worn or defective.
vReinstall all covers correctly before returning the
machine to the customer.
Electrical safety
Observe the following rules when working on electrical
equipment.
ImportantUse only approved tools and test equipment. Some
hand tools have handles covered with a soft
material that does not insulate you when working
with live electrical currents.
Many customers have, near their equipment, rubber
floor mats that contain small conductive fibers to
decrease electrostatic discharges. Do not use this
type of mat to protect yourself from electrical shock.
vFind the room emergency power-off (EPO) switch,
disconnecting switch, or electrical outlet. If an electrical
accident occurs, you can then operate the switch or
unplug the power cord quickly.
vDo not work alone under hazardous conditions or near
equipment that has hazardous voltages.
vDisconnect all power before:
–Performing a mechanical inspection
–Working near power supplies
–Removing or installing main units
vBefore you start to work on the machine, unplug the
power cord. If you cannot unplug it, ask the customer to
power-off the wall box that supplies power to the
machine and to lock the wall box in the off position.
vIf you need to work on a machine that hasexposed
electrical circuits, observe the following precautions:
–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.
