2. Informació important de seguretat
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. Configuració
3.1 Desembalatge i muntatge
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.
- Fixeu les rodes al marc del generador amb els elements de fixació proporcionats.
- Install the support legs to ensure stability.
- Attach the handle assembly to the frame.
3.2 Afegir oli 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 Afegir 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. Funcionament
4.1 Arrencada del generador
Ensure the generator is on a level surface and all electrical loads are disconnected before starting.
- Gireu la vàlvula de combustible a la posició 'ON'.
- Move the choke lever to the 'FULL CHOKE' position (if the engine is cold).
- Per Arrancada elèctrica: Press and hold the start button until the engine starts. Release the button once the engine is running.
- Per 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.
- Un cop el motor s'hagi engegat, moveu gradualment la palanca de l'estrangulador a la posició "RUN".
4.2 Connexió de càrregues elèctriques
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.
