Chapter 1. Read this first: Important safety information

This chapter contains the safety information that you must be familiar with.

General safety

Follow these rules to ensure general safety:

• Keep the areas around the computer clear and clean 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 across both feet.

3. Lift slowly. 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 would create a hazard for the customer, or would make the computer

unsafe.

• Before you start the computer, ensure that other service representatives and customer personnel are not

in a position that would create a hazard for them.

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

computer.

• Keep your tool case away from areas that people may walk through to ensure no-one trips 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, tie or fasten it back.

• Insert the ends of your necktie or scarf inside clothing or fasten it with a non-conductive 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.

• Reattach all covers correctly before returning the computer to the customer.
