Configuració
1. Preparació Inicial
Before first use, ensure the generator is placed on a flat, stable surface in a well-ventilated area, away from any combustible materials. The generator is shipped without oil or fuel.
Afegint oli de motor
- Locate the oil fill cap/dipstick on the side of the generator.
- Traieu el tap/varilla d'ompliment d'oli.
- Carefully add the recommended 10W-30 engine oil (provided) into the oil fill opening. The capacity is approximately 0.6 liters (20.3 fl oz).
- Comproveu el nivell d'oli amb la vareta de mesura; ha d'estar al límit superior.
- Col·loqueu de nou el tap/vareta d'ompliment d'oli de manera segura.

Instruccions de funcionament
Inici del generador
- Ensure the generator is properly set up and fueled.
- Gireu l'interruptor del motor a la posició "ON".
- If starting on gasoline, apply choke as needed. If starting on propane, ensure the propane tank valve is open.
- Estireu fermament la maneta de l'arrencador de retrocés fins que el motor arrenqui.
- Once started, gradually return the choke to the "RUN" position if used.
Ús de Outlets
The GX400BN offers various outlets for different power needs:
- Preses de corrent AC 120V 20A: Standard household outlets for general appliances.
- AC 120V 30A RV Outlet: Designed for RV hookups.
- Ports USB-A i USB-C: For charging sensitive electronics like phones and tablets.

Manteniment
Regular maintenance is crucial for the longevity and optimal performance of your generator. Always turn off the engine and allow it to cool before performing any maintenance.
Canvi d'oli
Change the engine oil after the first 20 hours of operation, and then every 100 hours or annually, whichever comes first. Refer to the oil fill section for location. Ensure the engine is warm for easier draining.
Inspecció/substitució de bugies
Inspect the spark plug every 100 hours or annually. Clean or replace if necessary. Use only the recommended spark plug type.
Neteja del filtre d'aire
Check and clean the air filter regularly, especially in dusty conditions. A dirty air filter can reduce engine performance and increase fuel consumption.
Emmagatzematge
For long-term storage, drain the fuel tank and carburetor (if using gasoline), or disconnect the propane tank. Store the generator in a clean, dry place.
