Generators are generators, and they need to be serviced on a regular basis to keep them running smoothly. Since many generators are used to provide backup power in the event of an emergency, it is critical for operators to check and inspect their gensets on a regular basis to ensure that they can perform as expected when required.

The manufacturer’s suggested generator maintenance routine is the highest, but all generator maintenance plans should include the following items at a minimum:

  • Inspection and removal of worn parts.
  • Checking of fluid levels, including coolant and fuel.
  • Inspection and cleaning of the battery.
  • Conducting of a load bank test on the generator and automatic transfer switch.
  • Checking of the control panel to ensure accuracy of readings and indicators.
  • Changing of the air and fuel filters.
  • Inspection of the cooling system.
  • Lubrication of parts as needed.

Keep a maintenance log for record-keeping purposes. Include all readings, fluid levels, and the date, as well as the generator’s hour meter reading. These documents may be linked to potential records to help predict anomalies or changes in activity, which could reveal hidden issues that, if left unchecked, may become major problems.

When properly maintained, generators will last for decades. These basic, small investments would pay off in the long run by avoiding costly repairs or even complete genset replacement. If you don’t have the resources to handle generator maintenance in-house, many generator dealers provide maintenance contracts or will refer you to someone who does. This will help you keep your generator in tip-top shape year after year after year. It’s time and money well spent if it can keep your business up and running when the power goes out.
