Computer, ATM, and office machine repairers install, fix, and maintain many of the machines that businesses, households, and other consumers use.

Computer, ATM, and office machine repairers typically do the following:

• Travel to customers' locations in response to service requests
• Communicate with customers to determine the source of a problem
• Do administrative tasks, such as completing work order forms
• Use a variety of tools, such as a multimeter, to help diagnose the problem
• Install large equipment, such as mainframe computers and ATMs
• Explain the basic functions of machines and equipment to customers
• Replace malfunctioning machine parts, such as video cards in desktop computers or keypads on ATM machines
• Provide preventative maintenance, such as cleaning the internal parts of machines
• Test newly installed systems to make sure they work properly

In most cases, machines do not break down entirely. Often just one broken part can keep a machine from working properly. Repairers often fix machines by replacing these parts and other defective equipment because it is often less expensive than replacing the entire machine.

Although the work of computer, ATM, and office machine repairers is very similar, the exact tasks differ depending on the type of equipment. For example, computer repairers often must replace desktop parts, such as a motherboard, because of hardware failure. ATM repairers may replace a worn magnetic head on a card reader to allow an ATM to recognize customers' bank cards. Office machine repairers replace parts of office machines that break down from general wear and tear, such as the printheads of inkjet printers.

Some repairers have assigned areas where they do preventive maintenance on a regular basis.

Computer repairers service and repair computer parts, network connections, and computer equipment, such as an external hard drive or computer monitor. Computer repairers must be familiar with various operating systems and commonly used software packages. Some work from repair shops, while others travel to customers' locations.

ATM repairers install and repair automated teller machines and, increasingly, electronic kiosks. They often work with a network of ATMs and travel to ATM locations when they are alerted to a malfunction.

Office machine repairers fix machinery at customers' workplaces because these machines are often large and stationary, such as office printers or copiers. Office machines often need preventive maintenance, such as cleaning, or replacement of commonly used parts as they break down from general wear and tear.

Mechanical engineering technicians help mechanical engineers design, develop, test, and manufacture industrial machinery, consumer products, and other equipment. They may make sketches and rough layouts, record and analyze data, make calculations and estimates, and report their findings.

Mechanical engineering technicians typically do the following:

• Evaluate drawing designs for new or changed tools by measuring dimensions on the drawing and comparing them with the original specifications
• Prepare layouts and drawings of parts to be made and the process for putting them together
• Discuss changes with coworkers--for example, in the design of the part, in the way it will be made and put together, and in the techniques and process they will use
• Review instructions and blueprints for the project to ensure the test specifications, procedures, and objectives
• Plan, make, and put together new or changed mechanical parts for products, such as industrial machinery or equipment
• Set up and conduct tests of complete units and of parts as they would really be used, as a way to investigate proposals for improving equipment performance
• Record test procedures and results, numerical and graphical data, and recommendations for changes in product or test methods
• Analyze test results in regarding design specifications and test objectives

Mechanical engineering technicians also estimate labor costs, equipment life, and plant space. Some test and inspect machines and equipment or work with engineers to eliminate production problems. They may assist in testing products by, for example, setting up instrumentation for vehicle crash tests.

Assemblers and fabricators assemble both finished products and the parts that go into them. They use tools, machines, and their hands to make engines, computers, aircraft, toys, electronic devices, and more.

Assemblers and fabricators typically do the following:

• Read and understand detailed schematics and blueprints
• Use hand tools or machines to assemble parts
• Conduct quality control checks
• Work closely with designers and engineers in product development 

Assemblers and fabricators have an important role in the manufacturing process. They assemble both finished products and the pieces that go into them. The products encompass a full range of manufactured products, including aircraft, toys, household appliances, automobiles, computers, and electronic devices.

Changes in technology have transformed the manufacturing and assembly process. Modern manufacturing systems use robots, computers, programmable motion-control devices, and various sensing technologies. These systems change the way in which goods are made and affect the jobs of those who make them. Advanced assemblers must be able to work with these new technologies and use them to produce goods.

The job of an assembler or fabricator ranges from very easy to very complicated, requiring a range of knowledge and skills. Skilled assemblers putting together complex machines, for example, read detailed schematics or blueprints that show how to assemble the machine. After determining how parts should connect, they use hand or power tools to trim, shim, cut, and make other adjustments to fit components together and align them properly. Once the parts are properly aligned, they connect them with bolts and screws or weld or solder pieces together.

Quality control is important throughout the assembly process, so assemblers look for faulty components and mistakes in the assembly process. They help to fix problems before defective products are made.

Manufacturing techniques are moving away from traditional assembly line systems toward lean manufacturing systems, which use teams of workers to produce entire products or components. Lean manufacturing has changed the nature of the assemblers' duties.

It has become more common to involve assemblers and fabricators in product development. Designers and engineers consult manufacturing workers during the design stage to improve product reliability and manufacturing efficiency. Some experienced assemblers work with designers and engineers to build prototypes or test products.

Although most assemblers and fabricators are classified as team assemblers, others specialize in producing one type of product or do the same or similar tasks throughout the assembly process.

The following are types of assemblers and fabricators:

Aircraft structure, surfaces, rigging, and systems assemblers fit, fasten, and install parts of airplanes, space vehicles, or missiles, such as wings, fuselage, landing gear, rigging and control equipment, or heating and ventilating systems.

Coil winders, tapers, and finishers wind wire coils of electrical components used in a variety of electric and electronic products, including resistors, transformers, generators, and electric motors.

Electrical and electronic equipment assemblers build products such as electric motors, computers, electronic control devices, and sensing equipment. Automated systems have been put in place because many small electronic parts are too small or fragile for human assembly. Much of the remaining work of electrical and electronic assemblers is done by hand during the small-scale production of electronic devices used in all types of aircraft, military systems, and medical equipment. Production by hand requires these workers to use devices such as soldering irons.

Electromechanical equipment assemblers assemble and modify electromechanical devices such as household appliances, computer tomography scanners, or vending machines. The workers use a variety of tools, such as rulers, rivet guns, and soldering irons.

Engine and machine assemblers construct, assemble, or rebuild engines, turbines, and machines used in automobiles, construction and mining equipment, and power generators.

Structural metal fabricators and fitters cut, align, and fit together structural metal parts and may help weld or rivet the parts together.

Fiberglass laminators and fabricators laminate layers of fiberglass on molds to form boat decks and hulls, bodies for golf carts, automobiles, or other products.

Team assemblers work on an assembly line, but they rotate through different tasks, rather than specializing in a single task. The team may decide how the work is assigned and how different tasks are done. Some aspects of lean production, such as rotating tasks and seeking worker input on improving the assembly process, are common to all assembly and fabrication occupations.

Timing device assemblers, adjusters, and calibrators do precision assembling or adjusting of timing devices within very narrow tolerances.

Electricians install and maintain electrical systems in homes, businesses, and factories.

Electricians typically do the following:

• Read blueprints or technical diagrams before doing work
• Install and maintain wiring and lighting systems
• Inspect electrical components, such as transformers and circuit breakers
• Identify electrical problems with a variety of testing devices
• Repair or replace wiring, equipment, or fixtures using hand tools and power tools
• Follow state and local building regulations based on the National Electric Code
• Direct and train workers to install, maintain, or repair electrical wiring or equipment

Almost every building has an electrical system that is installed during construction and maintained after that. Electricians do both the installing and maintaining of electrical systems.

Installing electrical systems is less complicated than maintaining older equipment. This is because it is easier to get to electrical wiring during construction. Maintaining older equipment, however, involves identifying problems and repairing malfunctioning equipment that is sometimes difficult to reach. Electricians doing maintenance work may need to fix or replace outlets, circuit breakers, motors, or robotic control systems.

Electricians read blueprints, which are technical diagrams of electrical systems that show the location of circuits, outlets, and other equipment. They use different types of hand and power tools, such as pipe benders, to run and protect wiring. Other commonly used hand and power tools include screwdrivers, wire strippers, drills, and saws. While troubleshooting, electricians also may use ammeters, voltmeters, and multimeters to find problems and ensure that components are working properly.

Many electricians work independently, but sometimes they collaborate with others. For example, experienced electricians may work with building engineers and architects to help design electrical systems in new construction. Some electricians also may consult with other construction specialists, such as elevator installers and heating and air conditioning workers, to help install or maintain electrical or power systems. At larger companies, electricians are more likely to work as part of a crew; they may direct helpers and apprentices to complete jobs.

The following are examples of occupational specialties:

Inside electricians maintain and repair large motors, equipment, and control systems in businesses and factories. They use their knowledge of electrical systems to help these facilities run safely and efficiently. Some also install the wiring for businesses and factories that are being built. To minimize equipment failure, inside electricians often perform scheduled maintenance.   

Residential electricians install wiring and troubleshoot electrical problems in peoples' homes. Those who work in new-home construction install outlets and provide access to power where needed. Those who work in maintenance and remodeling repair and replace faulty equipment. For example, if a circuit breaker is tripped, electricians determine the reason and fix it.

Line installers and repairers install or repair electrical power systems and telecommunications cables, including fiber optics.

Electrical power-line installers and repairers typically do the following:

• Drive work vehicles to job sites
• Install, maintain, or repair the power lines that move and distribute electricity
• Identify defective devices, circuit breakers, fuses, voltage regulators, transformers, and switches
• Inspect and test power lines and auxiliary equipment
• String power lines between poles, towers, and buildings
• Climb poles and transmission towers and use truck-mounted buckets to get to equipment
• Operate power equipment when installing and repairing poles, towers, and lines
• Follow safety standards and procedures

Telecommunications line installers and repairers typically do the following:

• Drive work vehicles to job sites
• Install, maintain, or repair telecommunications equipment
• Inspect or test lines or cables
• Lay underground cable, including fiber optic lines, directly in trenches
• Operate power equipment when installing and repairing poles, towers, and lines
• Set up service for customers

Every time you turn on your lights, call someone on the phone, watch cable television, or access the Internet, you are connecting to complex networks of physical power lines and cables that provide you with electricity and connect you with the outside world. Line installers and repairers, also known as line workers or linemen, are the people who install and maintain these networks.

Line installers and repairers typically specialize, and the areas in which they specialize depend on the network and industry in which they work:

Electrical power-line installers and repairers install and maintain the power grid--the network of power lines that moves electricity from generating plants to customers. They routinely work with high-voltage electricity, which requires extreme caution. This can range from hundreds of thousands of volts for the long-distance transmission lines that make up the power grid to less than 10,000 volts for distribution lines that supply electricity to homes and businesses.

Line workers who maintain the interstate power grid work in crews that travel to work locations throughout a large region to take care of transmission lines and towers. Workers employed by local utilities work mainly with lower voltage distribution lines, maintaining equipment such as transformers, voltage regulators, and switches. They may also work on traffic lights and street lights.

Telecommunications line installers and repairers install and maintain the lines and cables used by local and long-distance telephone services, cable television, the Internet, and other communications networks. These services use different types of cables, including fiber-optic cables. Unlike metallic cables that carry electricity, fiber-optic cables are made of glass or plastic and transmit signals using light. Working with fiber optics requires special skills, such as the ability to splice and finish off optical cables. Additionally, workers test and troubleshoot cables and networking equipment.

Because these systems are so complicated, many line workers also specialize by duty:

Line installers install new cable. They may work for construction contractors, utilities, or telecommunications companies. They generally start a new job by digging underground trenches or putting up utility poles and towers to carry the wires and cables. They use a variety of construction equipment, including digger derricks, which are trucks equipped with augers and cranes used to dig holes in the ground and set poles in place. Line installers also use trenchers, cable plows, and directional bore machines, which are used to cut openings in the earth to lay underground cables. Once the poles, towers, tunnels, or trenches are ready, line installers string cable along poles and towers or through tunnels and trenches.

Line repairers are employed by utilities and telecommunications companies that maintain existing power and telecommunications lines. Maintenance needs may be identified in a variety of ways, including remote monitoring equipment, inspections by airplane or helicopter, and customer reports of service outages. Line repairers often must replace aging or outdated equipment, so many of these workers have installation duties in addition to their repair duties.

When a problem is reported, line repairers must identify the cause and fix it. This usually involves testing equipment and replacing it as necessary. To work on poles, line installers usually use bucket trucks to raise themselves to the top of the structure, although all line workers must be adept at climbing poles and towers when necessary. Workers use special safety equipment to keep them from falling when climbing utility poles and towers.

Storms and other natural disasters can cause extensive damage to networks of power lines. When a connection goes out, line repairers must work quickly to restore service to customers.
