2. Safety Information
WARNING: Failure to follow these safety instructions could 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 in an enclosed area.
- CO Sensor: This generator is equipped with a Carbon Monoxide (CO) sensor that automatically shuts down the engine if unsafe levels of CO are detected. Do not disable or bypass this safety feature. If the CO sensor activates, move the generator to a well-ventilated area and allow it to clear before restarting.
- Fire Hazard: Gasoline and propane are highly flammable. Store fuel in approved containers in a well-ventilated area. Do not refuel while the engine is running or hot. Keep flammable materials away from the generator.
- Electrical Shock Hazard: Do not operate the generator in wet conditions. Ensure all electrical connections are secure and properly grounded. Never touch bare wires or receptacles with wet hands.
- Hot Surfaces: The generator's engine and muffler become very hot during operation and remain hot for some time after shutdown. Avoid contact to prevent burns.
- Proper Grounding: Always ground the generator properly before use to prevent electrical shock. Refer to local electrical codes for grounding requirements.
- Children and Pets: Keep children and pets away from the generator at all times.

4. Setup
4.1 Unpacking
Carefully remove the generator from its packaging. Inspect for any shipping damage. Retain packaging for future storage or transport.
4.2 Adding Engine Oil
The generator is shipped without engine oil. Before first use, add the recommended amount and type of oil. Refer to the engine section of this manual for oil specifications and capacity. Do not overfill.
4.3 Fueling the Generator
- Gasoline: Use fresh, unleaded gasoline with an octane rating of 87 or higher. Fill the fuel tank carefully, avoiding spills. Do not fill above the red indicator line.
- Propane (LPG): Connect the provided propane hose with regulator to a standard propane tank and to the generator's LPG inlet. Ensure all connections are tight to prevent leaks.
WARNING: Never mix oil with gasoline. Always refuel in a well-ventilated area with the engine off and cool.
4.4 Grounding the Generator
Connect a ground wire from the generator's ground terminal to a suitable earth ground (e.g., a ground rod). Consult local electrical codes for specific grounding requirements.
5. Operating Instructions
5.1 Starting the Generator
- Ensure the generator is on a level surface and properly grounded.
- Disconnect all electrical loads from the generator.
- Select the desired fuel type using the Fuel Selector Switch (Gas or LPG).
- Turn the Engine Switch to the 'ON' position.
- If starting on gasoline, pull the choke lever to the 'CHOKE' position (if engine is cold).
- Firmly pull the recoil starter handle until the engine starts.
- Once the engine starts, slowly push the choke lever back to the 'RUN' position (if used).
- Allow the engine to run for a few minutes to warm up before connecting electrical loads.
5.2 Stopping the Generator
- Disconnect all electrical loads from the generator.
- Turn the Engine Switch to the 'OFF' position.
- If using propane, close the valve on the propane tank.
5.3 Using ECO Mode
The Economy Switch allows the generator to adjust engine speed to match the load, improving fuel efficiency and reducing noise. To activate, turn the Economy Switch to 'ON'. For full power output or when starting high-load appliances, turn the Economy Switch to 'OFF'.
