Daily Inspection Checklist
- Check engine oil level, coolant level and fuel level before starting.
- Inspect for oil, coolant, diesel or exhaust leaks.
- Check battery voltage, terminals and charger status.
- Review controller alarms, emergency stop status and operating parameters.
- Check radiator airflow, fan belt condition and ventilation openings.
Weekly Inspection Checklist
- Run the generator under load where possible, not only idle operation.
- Inspect air filter restriction, fuel-water separator and hose condition.
- Check ATS panel status, mains failure simulation procedure and breaker condition.
- Clean dust around radiator, alternator air inlet and control cabinet.
Monthly Maintenance
Monthly maintenance should include battery load checks, coolant concentration, radiator cleaning, electrical terminal inspection, exhaust support inspection, vibration check and review of running hours. For standby generators, a controlled load test helps confirm that the system can carry the real building or factory load.
250-Hour and 500-Hour Service
| Interval | Typical work | Why it matters |
|---|---|---|
| 250 hours | Oil filter, engine oil, fuel filter check, air filter inspection, belt tension and coolant check | Reduces wear during long-hour operation and hot-site conditions |
| 500 hours | Replace filters as required, inspect radiator, alternator, breaker, ATS, mounts, hoses and wiring | Prevents overheating, electrical faults and unexpected shutdown |
Common Generator Problems in Nigeria
Common issues include clogged air filters, contaminated fuel, weak batteries, overheating, low coolant, blocked radiator fins, loose terminals, poor ventilation, low-load wet stacking and ATS control faults. A maintenance record helps detect repeated patterns before a major failure.

FAQ
How often should a diesel generator be serviced in Nigeria?
Daily visual checks are recommended during operation, with weekly and monthly inspections. Oil, oil filter, fuel filter and air filter intervals depend on engine model and site condition, but many industrial sites plan 250-hour and 500-hour service routines.
What should be checked daily?
Check oil level, coolant level, fuel level, battery voltage, leaks, abnormal noise, control panel alarms, radiator airflow and the surrounding area before or during operation.
Why do Nigerian sites need stricter maintenance?
Hot weather, dust, variable fuel quality, long outage hours and poor ventilation can increase filter blockage, overheating, battery failure and fuel-system problems.
When should I contact a generator service team?
Contact a service team if the generator has repeated alarms, overheating, low oil pressure, unstable voltage, fuel leaks, smoke, hard starting, ATS failure or abnormal vibration.
