Safety Information
This section contains the safety information with which you need to be familiar, before you service an IBM 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.

Grounding requirements
Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
Electrical safety
Important:
Use 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.
