Diesel Generator Technician Job Description

Knowing a generator service technician’s responsibilities and duties is helpful for those thinking about pursuing it as a career. As diesel engines provide power for a range of applications, a technician is going to help ensure that they are running properly.

Diesel generator mechanics need to be able to perform a variety of duties related to diesel engines and related systems. Some of their daily tasks might include:

• Installing new equipment and systems.
• Running load bank tests on generators.
• Performing voltage changes.
• Rewiring and installing control panels and voltage regulators.
• Preparing generators for shipment.
• Performing preventative maintenance, including checking for worn parts and leaks.
• Maintaining records of repairs and maintenance performed on equipment.
• Calibrating and inspecting equipment.
• Transporting equipment and diesel mechanic tools from various work sites.

Electrical Troubleshooting and Safety

A diesel generator technician needs to take into account electrical safety and electrical troubleshooting protocols. Technicians need to wear appropriate personal protective equipment (PPE) when working on these systems.

Different levels of PPE exist depending on the flash and shock hazard boundaries of the job. Before working, inspections of the tools, cables and equipment take place to ensure things do not look incomplete, damaged or worn.

Electrical equipment, including conductors and circuit parts, is put into a safe working condition before being worked on. This means de-energizing these parts. Energized work is only permitted when it’s determined a greater risk exists otherwise or equipment design prevents de-energized work.

Generator technicians perform job safety plans before starting work, which includes describing the job, identifying hazards, performing shock and arc risk assessments and listing work procedures. Doing these things helps ensure everyone is safe while working.
