Besides receptacles and circuit breakers, the control panel has a variety of user-friendly features. They include a recoil cord starter, a Power Dial, an Hour Meter, an Eco Mode, parallel connectors, and a grounding lug. Three LEDs provide you with information about the generator's readiness for connections (green), an overload condition (red), and low oil level (yellow). If the oil level drops below a safe point the engine stops automatically. You won't be able to get it going again until you've added more oil.
You use the Hour Meter to keep an eye on when it's necessary to carry out scheduled maintenance. Carefully following the manual's guidance on this should extend the generator's useful life.
The Eco Mode switch ensures the quietest operation, improves fuel efficiency, and reduces emissions. It's used when you only need to power small appliances, such as a TV, lights, a radio, or a video game. It should be in the Off position when connecting motor-driven equipment that turn on and off, such as an RV air conditioner, and resistive loads like a hair dryer.
