Assemble, install, repair, or maintain electric or hydraulic freight or passenger elevators, escalators, or dumbwaiters.
- Assemble, install, repair, and maintain elevators, escalators, moving sidewalks, and dumbwaiters, using hand and power tools, and testing devices such as test lamps, ammeters, and voltmeters.
- Test newly installed equipment to ensure that it meets specifications, such as stopping at floors for set amounts of time.
- Locate malfunctions in brakes, motors, switches, and signal and control systems, using test equipment.
- Check that safety regulations and building codes are met, and complete service reports verifying conformance to standards.
- Connect electrical wiring to control panels and electric motors.
- Adjust safety controls, counterweights, door mechanisms, and components such as valves, ratchets, seals, and brake linings.
- Read and interpret blueprints to determine the layout of system components, frameworks, and foundations, and to select installation equipment.
- Inspect wiring connections, control panel hookups, door installations, and alignments and clearances of cars and hoistways to ensure that equipment will operate properly.

- Install electrical wires and controls by attaching conduit along shaft walls from floor to floor and pulling plastic-covered wires through the conduit.
- Cut prefabricated sections of framework, rails, and other components to specified dimensions.
- Operate elevators to determine power demands, and test power consumption to detect overload factors.
- Assemble electrically powered stairs, steel frameworks, and tracks, and install associated motors and electrical wiring.
