As an industrial machinery mechanic, your duties are to repair and maintain industrial equipment, such as factory machines and production/packaging equipment. Your responsibilities are to make routine maintenance and safety inspections of the equipment, test machines before the factory prepares for a full production run, provide a diagnosis of any technical problems you encounter, and either repair the equipment or place an order for new parts. Mechanics often seek to find any errors or issues before they become significant problems for the facility. Maintenance workers deal with issues after they have become severe.
