What is Generator Maintenance?
Generator maintenance is the process of sustaining a commercial or industrial generator’s peak condition through regular inspections, repairs, and monitoring. Maintaining generators are typically done by in-house engineers and generator dealers to ensure a unit’s reliability, efficiency, and lower operating costs, more specifically:
A basic diesel generator maintenance checklist is used to ensure diesel generators provide good power quality. Engineers and operators can follow this template as a guide when performing the following during inspections:
- Perform physical and visual inspection of diesel generator
- Take photo evidence of leakage, damage, and defects
- Check the battery, oil, and fuel condition
- Provide overall condition assessment of diesel generator
- Conclude the inspection with a digital signature and timestamp
Below is an example of diesel generator maintenance report that can be generated using the iAuditor mobile app.
- Reliability – ensure that the battery and engine are in peak working condition at all times
- Efficiency – maintain optimum performance
- Lower operating costs – early detection of defects and damage before they worsen

The NFPA standard for emergency and standby power systems require businesses to provide an alternate source of electricity when unplanned power outages occur. Depending on the nature of the establishment, an unexpected power outage could range from a simple inconvenience (a shopping mall) to downright fatalities (intensive care units). It is important that generator maintenance inspections are regularly performed in order to avoid such problems from occurring.
A generator maintenance checklist typically includes:
- Physical and visual checks of the diesel generator;
- Leakage checks of engine, exhaust, cooling, fuel, and DC electrical systems;
- Oil and lubrication services;
- Battery testing;
- Overall condition assessment; and
- Signature, date, and time of inspection.
In-house engineers and professionals may not always be available to perform generator maintenance tasks. Here are some easy diesel generator maintenance tips for non-experts:
- Run the generator every 3 to 6 months – Diesel fuel degrades if it sits idle, which is why it’s ideal to run the generator for a few minutes every 3 to 6 months to keep it from corroding. This also gives assurance that the generator is in good working condition.
- Check for signs of damage – Observe the case, fuel system, exhaust system, and engine for holes, cracks, and fuel or oil leaks. It is essential that leaks are spotted immediately before they turn into a fire hazard.
- Clean the generator regularly – Remove visible dirt, mud, dust, and other irregularities from your generator on a regular basis. This can help ensure that external elements do not affect the generator’s operation.
Missing audit reports and documentation logs are just some of the issues you’re susceptible to by relying on paper-based inspections. Losing a generator’s history of readings, parameters and damages can be problematic, leading to double the work. Replacing your paper checklist with a reliable mobile inspection app like iAuditor can maximize your diesel generator’s usability.
iAuditor by SafetyCulture can replace your entire paper trail with one online platform. Perform paperless generator maintenance inspections, take photo evidence of damaged items or equipment, and automatically secure all records via unlimited cloud-storage.
iAuditor can also help you schedule your generator maintenance and send reminders so you’ll never miss another inspection again. To save you time, we have built sample Generator Maintenance Checklist Templates that are 100% customizable and you can download for free!
Featured Maintenance Checklists for Commercial and Industrial Generators
A diesel generator maintenance and testing checklist is used to ensure that the generator is in good working condition and that power supply tests are conducted. It is used by engineers to log defects and record electricity tests. Perform the following when completing the form:
- Collect general Information provided by the manufacturer of the diesel generator
- Check the condition of equipment, engine, and control system
- Perform electrical testing
- Record findings and provide recommendations
- Affix engineer/operator digital signature to validate the test
A generator inspection checklist is used to evaluate engineers/operators performance when conducting generator maintenance. This template can be used by supervisors to ensure maintenance procedures are followed. Perform these steps when completing the form:
- Check the working condition of the diesel generator before and after starting it
- Record recommendations and overall condition assessment
- Capture electronic signature of engineer/operator and countersigned by the supervisor
