Yeah, that's the hour meter function. It's not a problem, it's just telling you how many hours are on the machine.
When you start the engine, the green output indicator blinks a specific number of times to indicate the total cumulative operating hours. Here's the code:
- No blinks: 0–100 hours
- 1 blink: 100–200 hours
- 2 blinks: 200–300 hours
- 3 blinks: 300–400 hours
- 4 blinks: 400–500 hours
- 5 blinks: 500 or more hours
It only does this at startup. Once it's running, the green light should stay steadily on, which means it's producing power normally at the receptacles.
If the green light is off while running: That's a problem. It means there's no output. Check if the overload indicator (red) is on, which would mean you tripped it with too much load or a short. Disconnect everything and let it reset.
Heads up: That hour count is useful for tracking maintenance intervals for things like oil changes and air filter cleaning.
