FAQs About Generator Maintenance
How often should a generator be serviced?
Most manufacturers recommend servicing standby generators at least once a year or every 100-200 hours of use, whichever comes first.
Can I do generator maintenance myself?
Some basic tasks, like checking oil levels or cleaning debris, are DIY-friendly. However, full maintenance and diagnostics should be handled by a qualified technician to avoid safety risks and maintain warranty coverage.
How do I know if my generator needs service?
Signs that your generator may need servicing include trouble starting, unusual noises or vibrations, warning lights on control panels, irregular voltage output, and leaks or low fluid levels. If you notices any of these signs, it’s important to schedule generator maintenance right away.
Do generators need oil changes?
Yes. Oil lubricates the engine and must be changed regularly, typically every 50–100 hours of use or annually. Always use the oil type recommended by the manufacturer.
Should I run my generator regularly even if I don’t need it?
Yes. Running your generator under load for 10–15 minutes once a month helps keep internal parts lubricated, prevents fuel degradation, and ensures it’s ready when needed.
