Safety information

The following section contains 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 objects that weigh 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 tool case 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. Ensure 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.
