Important Safety Information

Failure to follow these instructions may result in serious injury or death.

• Carbon Monoxide Hazard: Generators produce carbon monoxide (CO), an odorless, colorless, and poisonous gas. Operate the generator outdoors only, far away from windows, doors, and vents. Never operate indoors, in a garage, or in any enclosed space.
• Fire Hazard: Gasoline is highly flammable. Always refuel in a well-ventilated area with the engine off and cooled. Do not smoke or allow open flames near the generator.
• Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all connections are secure and dry. Never connect the generator directly to your home's electrical system without a transfer switch installed by a qualified electrician.
• Hot Surfaces: The generator's engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid touching hot surfaces to prevent burns.
• CO Sensor: This generator is equipped with a CO sensor that will shut down the engine if carbon monoxide levels become dangerously high. Do not disable or bypass this safety feature.

Setup and First Use

1. Unpacking

Carefully remove the generator from its packaging. Inspect for any shipping damage. Retain packaging materials for future storage or transport.

2. Add Engine Oil

The generator is shipped without engine oil. Before starting, add the recommended type and amount of oil (refer to specifications for details). Place the generator on a level surface. Remove the oil fill cap/dipstick, slowly pour in the oil, and check the level using the dipstick. Do not overfill.

3. Add Fuel

Use fresh, unleaded gasoline with an octane rating of 87 or higher. Ensure the generator is off and cool before refueling. Open the fuel cap and carefully pour gasoline into the fuel tank, avoiding overfilling. Securely replace the fuel cap.

4. Initial Startup Procedure

1. Place the generator on a flat, outdoor surface, away from any structures or vents.
2. Ensure no electrical devices are connected to the generator.
3. Turn the fuel valve to the "ON" position.
4. Move the engine switch to the "ON" position.
5. Pull the choke lever to the "CHOKE" position (if the engine is cold).
6. Grasp the recoil starter handle firmly and pull it slowly until resistance is felt, then pull quickly and smoothly. Repeat until the engine starts.
7. Once the engine starts, slowly move the choke lever to the "RUN" position.
8. Allow the generator to run for a few minutes to warm up before connecting any loads.

• AC Outlets (120V): Connect your standard household appliances.
• DC Outlet (12V): For charging 12V batteries or powering DC devices.
• USB Ports (5V): For charging mobile devices and other USB-powered electronics.
• ECO Switch: Engages Eco-mode for improved fuel efficiency and quieter operation under light loads.
• Parallel Kit Terminal: Allows connection of two compatible AMERISUN inverter generators for increased power output.
• Indicator Lights: Monitor power output, oil level, and overload status.

Connecting Electrical Devices

Once the generator is running and warmed up, you can connect your electrical devices. Ensure the total wattage of connected devices does not exceed the generator's running wattage (1900W) to prevent overload. Connect devices one at a time.

Using Eco Mode

For optimal fuel efficiency and reduced noise, activate the ECO mode when operating under light loads. The engine speed will automatically adjust to match the load, saving fuel and extending runtime.

Stopping the Generator

1. Disconnect all electrical devices from the generator.
2. Allow the generator to run for a few minutes without load to cool down.
3. Turn the engine switch to the "OFF" position.
4. Turn the fuel valve to the "OFF" position.
