Removal and Replacement PreliminariesMaintenance and Service Guide4–54.6 Workstatinon PrecautionsUse the following grounding precautions at workstations:n Cover the workstation with approved static-shielding material (refer to Table 4-2, “Static-Shielding Materials”).n Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment.n Use conductive field service tools, such as cutters, screwdrivers, and vacuums.n When using fixtures that must directly contact dissipative surfaces, only use fixtures made of static-safe materials.n Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids and Styrofoam.n Handle electrostatic-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these items only at static-free workstations.n Avoid contact with pins, leads, or circuitry.n Turn off power and input signals before inserting or removing connectors or test equipment.
