2. Safety Information
Your safety is paramount. Please read and understand all safety warnings and instructions before operating the generator. Failure to do so may result in serious injury or death.
- Carbon Monoxide (CO) Hazard: Generators produce carbon monoxide, an odorless, colorless, and poisonous gas. Operate the generator outdoors in a well-ventilated area, far away from windows, doors, and vents. Never operate indoors, in a garage, or in any enclosed space.
- CO-Sensor: This generator is equipped with a CO-Sensor that automatically shuts down the engine if carbon monoxide levels become dangerously high. Do not disable or bypass this safety feature.
- Low Oil Level Shutdown: The generator will automatically shut down if the engine oil level is too low to prevent engine damage. Always check the oil level before each use.
- Overload Protection: The unit includes overload protection to prevent damage to the generator and connected devices. Do not exceed the rated wattage.
- Fuel Safety: Gasoline is highly flammable. Store fuel in approved containers in a well-ventilated area away from ignition sources. Refuel only when the engine is off and cool.

3. Setup
Before first use, proper setup is crucial for safe and efficient operation.
3.1 Unpacking and Initial Inspection
Carefully remove the generator and all accessories from the packaging. Inspect for any signs of damage during shipping. Ensure all components listed in the packing list are present, including the oil funnel and tools.

3.2 Adding Engine Oil
The generator is shipped without engine oil. You must add the correct type and amount of oil before starting. Use 10W-30 oil.
- Place the generator on a level surface.
- Locate the oil fill cap/dipstick.
- Remove the cap and use the provided funnel to slowly add the recommended amount of 10W-30 engine oil. Do not overfill.
- Replace the oil fill cap/dipstick securely.
3.3 Adding Fuel
Use fresh, unleaded gasoline with an octane rating of 87 or higher. Do not use E85 or mixed fuels.
- Ensure the generator is off and cool.
- Unscrew the fuel cap.
- Slowly add gasoline to the fuel tank (1.6-gallon capacity), being careful not to overfill. Leave some space for expansion.
- Securely replace the fuel cap.
