[Jining，2025.7.18] – CNMC Group, a leading provider of power generation solutions, shares expert generator maintenance guidelines to help businesses maximize uptime and avoid costly breakdowns. Whether you rely on diesel generators, gas-powered units, or industrial generator sets, proper care ensures reliable backup power during critical operations.
5 Must-Follow Generator Maintenance Practices
1.Regular Oil & Filter Changes
Diesel and gas generators require scheduled oil changes (every 50-500 hours, depending on usage).
Always use manufacturer-approved filters to prevent contaminants from damaging the engine.
2.Battery Inspection & Testing
A faulty battery is the #1 cause of generator failure during power outages.
Check terminals for corrosion and test voltage monthly.
3.Cooling System Maintenance
Clean radiator fins and check coolant levels to prevent overheating—critical for standby generators in hot climates.
4.Fuel System Care
Use fuel stabilizers for stored diesel to prevent degradation.
Drain condensation from tanks to avoid microbial growth (common in industrial generators).
5.Load Bank Testing
Annual under-load testing verifies performance and burns off carbon buildup in heavy-duty generator sets.
When to Schedule Professional Servicing?
✔ Routine checks (Monthly/Quarterly) – Fluid levels, belts, hoses
✔ Annual comprehensive inspection – Alternator, voltage regulator, exhaust system
✔ Post-emergency use – After prolonged operation during power outages
