• Light use (backup): Typically a basic check by starting the generator should occur every month, then a full service can be 6 monthly or 12 monthly.
• Heavy or continuous use: Every 250–500 hours for diesel powered generators. Then every 50-150 hours for Petrol powered generators.Regular servicing helps prevent failure and extends generator lifespan. It also alerts you to any potential issues before they become a problem.
