Our routine diesel generator maintenance checklist template helps you establish a systematic approach to generator upkeep, ensuring reliability when you need backup power most. The template covers all critical systems—from fuel and cooling to electrical components—with clear inspection points for daily, weekly, and monthly checks. You’ll document fluid levels, filter conditions, and performance metrics to catch small issues before they cause major failures.
According to a study in Applied Energy, well-maintained diesel generators are only 20% likely to fail within two weeks of continuous operation, while poorly maintained units have a 50% failure risk within just 48 hours. By implementing this structured maintenance routine, you’ll extend your generator’s lifespan, reduce repair costs, and maintain power reliability during critical situations.
