2. Información importante de seguridade
Always operate the generator outdoors in a well-ventilated area, far away from windows, doors, and vents to prevent carbon monoxide accumulation. Carbon monoxide is an odorless, colorless gas that can cause serious injury or death. The generator is equipped with COsense Technology, which automatically shuts down the unit if hazardous levels of carbon monoxide are detected. Ensure the exhaust is pointed away from occupied areas.
Read and understand the entire owner's manual before operating the generator. Keep children and pets away from the generator during operation. Always ensure proper grounding of the unit.
3. Configuración
3.1 Desembalaxe e montaxe
Carefully remove the generator and all components from the packaging. Inspect for any shipping damage. The package typically includes the generator, owner's manual, engine oil, oil funnel, wheels, and necessary hardware for assembly.
- Attach the wheels to the generator frame using the provided hardware.
- Install the support legs to ensure stability.
- Attach the handle assembly to the frame.
3.2 Engadir aceite de motor
The generator is shipped without engine oil. Before first use, add the recommended amount of 10W-30 engine oil (approximately 1.2 quarts or 1.1 liters) using the provided funnel. Do not overfill. The low-oil pressure shutdown feature will prevent the engine from starting or running if the oil level is too low.
3.3 Engadir combustible
Use fresh, unleaded gasoline with an octane rating of 87 or higher. The fuel tank has a large capacity of 14.2 Imperial Gallons (approximately 17 US gallons). Fill the tank slowly to avoid spills. Do not fill the tank completely to allow for fuel expansion. Always ensure the fuel cap is securely tightened after filling.

4. Funcionamento
4.1 Arranque do xerador
Asegúrese de que o xerador estea sobre unha superficie nivelada e de que todas as cargas eléctricas estean desconectadas antes de arrincalo.
- Xire a válvula de combustible á posición "ON".
- Move the choke lever to the 'FULL CHOKE' position (if the engine is cold).
- Para Arranque eléctrico: Press and hold the start button until the engine starts. Release the button once the engine is running.
- Para Manual Pull Start: Grasp the recoil starter handle and pull slowly until resistance is felt, then pull quickly and firmly. Repeat if necessary until the engine starts.
- Unha vez que o motor arranque, mova gradualmente a panca do estrangulador á posición "RUN".
4.2 Conexión de cargas eléctricas
The generator features multiple outlets, including 120V AC and 120V/240V AC options. Connect your appliances or extension cords to the appropriate outlets. The TruePower Technology ensures less than 5% Total Harmonic Distortion (THD), making it safe for sensitive electronics.

4.3 Monitoring and Shutdown
Monitor the fuel gauge to ensure continuous operation. The generator provides a long runtime, offering up to 9 hours at 50% load. To shut down the generator, first disconnect all electrical loads, then turn the engine switch to 'OFF', and finally turn the fuel valve to 'OFF'.
5. Mantemento
Regular maintenance is crucial for the longevity and optimal performance of your generator. Refer to the owner's manual for a detailed maintenance schedule.
- Aceite de motor: Comprobe o nivel de aceite antes de cada uso. Cambie o aceite do motor despois das primeiras 20 horas de funcionamento e, a continuación, cada 100 horas ou anualmente.
- Filtro de ar: Inspeccione e limpe o filtro de aire cada 50 horas ou con máis frecuencia en lugares con moito po. Substitúao se está danado.
- Buxía: Inspect and clean the spark plug every 100 hours. Replace if worn or fouled.
- Sistema de combustible: Drain the fuel system if storing the generator for more than 30 days to prevent fuel degradation. Use a fuel stabilizer if draining is not possible.
