Hardware Maintenance Manual Safety information 2 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.
Chapter 2. Safety information •• 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.
Hardware Maintenance Manual •• If you need to work on a machine that has exposed electrical circuits, observe the following precautions: – Ensure that another person, familiar with the power-off controls, is near you. Remember: 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. Remember: There must be a complete circuit to cause electrical shock.
Chapter 2. Safety information Safety inspection guide The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of features or options not covered by this inspection guide.
Hardware Maintenance Manual Handling electrostatic discharge-sensitive devices Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge. Notes: 1.
Chapter 2. Safety information Safety notices The caution and danger safety notices in this section are provided in the the language of English. DANGER Electrical current from power, telephone and communication cables is hazardous.
