Install, service, or repair opening and closing mechanisms of automatic doors and hydraulic door closers. Includes garage door mechanics.

Adjust doors to open or close with the correct amount of effort, and make simple adjustments to electric openers. Apply hardware to door sections, such as drilling holes to install locks. Assemble and fasten tracks to structures or bucks, using impact wrenches or welding equipment . Bore and cut holes in flooring as required for installation, using hand tools and power tools. Carry springs to tops of doors, using ladders or scaffolding, and attach springs to tracks in order to install spring systems. Clean door closer parts, using caustic soda, rotary brushes, and grinding wheels. Cover treadles with carpeting or other floor covering materials and test systems by operating treadles. Cut door stops and angle irons to fit openings. Fasten angle iron back-hangers to ceilings and tracks, using fasteners or welding equipment. Inspect job sites, assessing headroom, side room, and other conditions in order to determine appropriateness of door for a given location. Install dock seals, bumpers, and shelters. Install door frames, rails, steel rolling curtains, electronic-eye mechanisms, and electric door openers and closers, using power tools, hand tools, and electronic test equipment. Lubricate door closer oil chambers and pack spindles with leather washers. Remove or disassemble defective automatic mechanical door closers, using hand tools. Repair or replace worn or broken door parts, using hand tools. Run low voltage wiring on ceiling surfaces, using insulated staples. Set doors into place or stack hardware sections into openings after rail or track installation. Set in and secure floor treadles for door activating mechanisms; then connect power packs and electrical panelboards to treadles. Study blueprints and schematic diagrams in order to determine appropriate methods of installing and repairing automated door openers. Wind large springs with upward motion of arm. Collect payment upon job completion. Complete required paperwork, such as work orders, according to services performed or required. Fabricate replacements for worn or broken parts, using welders, lathes, drill presses, and shaping and milling machines. Operate lifts, winches, or chain falls in order to move heavy curtain doors. Order replacement springs, sections, and slats.
