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.
Observe the following rules when working on electrical equipment. 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.
– Send another person to get medical aid. 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.
• Avoid contact with other people while handling the part. • Wear a grounded wrist strap against your skin to eliminate static on your body. • Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. • Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices.
To Connect To Disconnect 1. Turn everything OFF. 1. Turn everything OFF. 2. First, attach all cables to devices. 2. First, remove power cords from outlet. 3. Attach signal cables to connectors. 3.
