Supplemental

• Maintain stocks of parts.
• Rewire electrical systems, and repair or replace electrical accessories.
• Solder, wrap, and coat wires to ensure proper insulation.
• Assemble electrical parts such as alternators, generators, starting devices, and switches, following schematic drawings and using hand, machine, and power tools.
• Remove and replace defective parts such as coil leads, carbon brushes, and wires, using soldering equipment.
• Reface, ream, and polish commutators and machine parts to specified tolerances, using machine tools.
• Clean cells, cell assemblies, glassware, leads, electrical connections, and battery poles, using scrapers, steam, water, emery cloths, power grinders, or acid.
• Rewind coils on cores in slots, or make replacement coils, using coil-winding machines.
• Cut and form insulation, and insert insulation into armature, rotor, or stator slots.
• Set machinery for proper performance, using computers.
• Drain and filter transformer oil and refill transformers with oil until coils are submerged.
• Position and level battery cells, anodes, or cathodes, using hoists or leveling jacks, or signal other workers to perform positioning and leveling.
• Verify and adjust alignments and dimensions of parts, using gauges and tracing lathes.
• Test equipment for overheating, using speed gauges and thermometers.
• Bolt porcelain insulators to wood parts to assemble hot stools.
• Pour compounds into transformer-case terminal openings to seal out moisture.
• Test conditions, fluid levels, and specific gravities of electrolyte cells, using voltmeters, hydrometers, and thermometers.
• Clean, rinse, and dry transformer cases, using boiling water, scrapers, solvents, hoses, and cloths.
• Inspect batteries for structural defects such as dented cans, damaged carbon rods and terminals, and defective seals.
• Steam-clean polishing and buffing wheels to remove abrasives and bonding materials, and spray, brush, or recoat surfaces as necessary.
• Test battery charges, and replace or recharge batteries as necessary.
• Repair and operate battery-charging equipment.
• Add water or acid to battery cell solutions to obtain specified concentrations.
• Sharpen tools such as saws, picks, shovels, screwdrivers, and scoops, either manually or by using bench grinders and emery wheels.
• Seal joints with putty, mortar, and asbestos, using putty extruders and knives.
• Hammer out dents and twists in tools and equipment.
