A generator's only job is to start when the power fails, and most failures are small things: a weak battery, low fuel, a loose terminal. A DG set maintenance checklist used by the site and on every AMC visit catches them. Download the CSV below. Follow the engine and alternator makers' instructions.
DG set maintenance checklist: site checks (daily or weekly)
- Fuel level in the tank and day tank
- Engine oil and coolant levels
- Battery charger on; no warning lights
- Visible leaks of fuel, oil or coolant
- Running hours noted in the log
AMC visit checks (monthly)
- Test run, on load if possible; voltage, frequency, oil pressure, temperature
- Battery voltage, terminals clean and tight, electrolyte if applicable
- Belts: tension and wear
- Air filter restriction indicator
- Radiator: fins clean, hoses sound
- Control panel, alarms, auto start and changeover
- Exhaust: leaks, mounting
Services by running hours
Oil, oil filter, fuel filter, air filter and coolant are changed at the running hours or time interval the engine maker specifies, whichever comes first. Record the next due hours on the log.
Read the log for trouble
- Oil consumption rising between visits
- Battery voltage dropping visit after visit
- Frequent alarms or failed auto starts
DGs on the AMC record
Use this checklist on visits under the DG set AMC format, and keep the history in the maintenance log book. ServicePilot keeps each DG as equipment on the client's site and creates AMC visits on schedule.
