Heavy equipment repair technicians may be required to operate heavy equipment as part of the diagnostic process. They may need to disassemble and reassemble heavy equipment, order new parts and conduct inspections on heavy machinery to ensure proper functioning and compliance with manufacturer standards. Technicians may also need to possess the ability to read and comprehend blueprints, instructional manuals and technical sketches.

Technicians may need to work with a range of tools, such as wrenches, hex keys, flame cutters and vise grips. Since the work environment of technicians may be hazardous and polluting, these professionals may also need to master appropriate safety and health protocols and procedures. The physical demands of the job - crouching, stooping, climbing and pushing - require technicians to stay in good physical condition.

Although a high school diploma or its equivalent is the minimum educational requirement for most repair technician positions, employers may prefer individuals who understand mechanics and who are acquainted with areas such as large engines, computer systems and hydraulics. Individuals with no knowledge in these areas may elect to enroll in either a certificate or associate's degree program in heavy equipment repair

Students in certificate programs may be required to learn the principles of heavy engine rebuilding, power trains and industrial safety. Those in the associate's degree programs may be required to take a broader curriculum emphasizing mathematics, applied science, communications and writing in addition to core subjects.
