Chapter 2. Safety information

This chapter contains the safety information that you need to be familiar with before servicing a computer.

General safety

Follow these rules to ensure general safety:

•Observe good housekeeping in the area of the machines during and after maintenance.

•When 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.

•Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.

•Before you start the machine, ensure that other service representatives and the customer’s personnel are not in a hazardous position.

•Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine.

•Keep your tool case away from walk areas so that other people will not trip over it.

•Do 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.

•Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approximately 8 centimeters (3 inches) from the end.

•Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing. Remember: Metal objects are good electrical conductors.

•Wear 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.

•After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.

•Reinstall all covers correctly before returning the machine to the customer.

Electrical safety

CAUTION:

Electrical current from power, telephone, and communication cables can be hazardous. To avoid personal injury or equipment damage, disconnect the attached power cords, telecommunication systems, networks, and modems before you open the computer covers, unless instructed otherwise in the installation and configuration procedures.
