2. Informació de seguretat
La vostra seguretat és primordial. Seguiu sempre les següents pautes de seguretat:
- Perill de monòxid de carboni: Generators produce carbon monoxide, an odorless, colorless gas that can kill you. ALWAYS operate the generator outdoors in a well-ventilated area, far from windows, doors, and vents. Never operate indoors, in a garage, or in any enclosed space.
- Perill d'incendi: Fuel is highly flammable. Refuel in a well-ventilated area with the engine off and cool. Do not smoke or use open flames near the generator.
- Perill de descàrrega elèctrica: Do not operate the generator in wet conditions. Ensure proper grounding.
- Superfícies calentes: The generator's engine and muffler become very hot during operation. Avoid contact to prevent burns.
- Llegeix el manual: Familiarize yourself with all controls and features before operating.

4. Configuració
4.1 Afegir oli de motor
- Col·loqueu el generador sobre una superfície plana.
- Locate the oil fill cap (Figure 4).
- Traieu el tap d'ompliment d'oli i la vareta.
- Carefully pour the recommended SAE 10W-30 engine oil into the oil fill opening using the provided funnel. The oil capacity is 0.63 quarts (0.6L).
- Comproveu el nivell d'oli amb la vareta de mesura; ha d'estar al límit superior.
- Torneu a col·locar el tap d'ompliment d'oli de manera segura.

4.2 Afegir combustible
This model operates on gasoline. Ensure the engine is off and cool before adding fuel.
- Locate the fuel tank cap (Figure 4).
- Desenrosqueu la tapa del dipòsit de combustible.
- Carefully pour fresh, unleaded gasoline (minimum 87 octane) into the fuel tank. Do not overfill; leave space for fuel expansion. The tank volume is 1.9 gallons.
- Torneu a col·locar el tap del dipòsit de combustible de manera segura.
4.3 Connexió a terra del generador
Always ground the generator before operation to prevent electrical shock. Connect a grounding wire (not included) from the generator's grounding terminal to an external grounding rod or suitable ground source.

The control panel (Figure 5) features:
- Data Meter: Mostra voltage, frequency, runtime, and fuel level.
- Eco-Mode Switch: Toggles between standard and eco-friendly operation.
- Botó de restabliment: Resets the generator in case of overload.
- 120V NEMA 5-20R Receptacles (x4): Endolls domèstics estàndard.
- 120V TT-30R RV Receptacle (x1): For RV applications.
- DC 12V Receptacle (x1): For 12-volt DC devices.
- DC 5V USB Ports (x2): Per carregar petits dispositius electrònics.
- Parallel Connect Ports: Allows connection of two WEN inverter generators for increased power (requires WEN Parallel Connection Kit, sold separately).
- Terminal de terra: Per a un funcionament segur.
5.2 Starting the Generator (Recoil Start)
- Assegureu-vos que el generador estigui sobre una superfície plana i correctament connectat a terra.
- Comproveu els nivells d'oli i combustible.
- Turn the 4-in-1 switch (Figure 6) to the SOCOLAR posició.
- Gently pull the recoil starter handle 3-5 times to prime the engine.
- Quickly pull the recoil starter handle to start the engine.
- Once the engine starts, slowly turn the 4-in-1 switch to the CÓRRER posició.

5.3 Connexió de dispositius
Once the generator is running, you can connect your electrical devices to the appropriate outlets on the control panel. Ensure the total wattage of connected devices does not exceed 4000 rated watts.
5.4 Eco-Mode Operation
Engage the Eco-Mode switch (Figure 5) to allow the generator's engine to automatically adjust its fuel consumption based on the load. This conserves fuel and reduces noise when full power is not required.
5.5 Aturar el generador
- Desconnecteu tots els aparells elèctrics del generador.
- Turn the 4-in-1 switch to the COMBUSTIBLE OFF position. Allow the engine to run until it stops from lack of fuel (this drains the carburetor).
- Once the engine has stopped, turn the 4-in-1 switch to the MOTOR APAGAT posició.
6. Manteniment
Un manteniment regular garanteix un rendiment òptim i allarga la vida útil del generador.
6.1 Fuel Shutoff Feature
The fuel shutoff feature is designed to minimize maintenance by allowing the generator to use up remaining fuel from the carburetor before shutting down. This prevents the build-up and blockages caused by stagnant fuel, which can prolong the unit’s lifespan.
6.2 Oil and Air Filter Access
To access the oil and air filter for maintenance, remove the designated access panel. This allows for quick and easy oil changes and air filter cleaning/replacement.
7. Solució De Problemes
If your generator encounters issues, refer to the following common troubleshooting steps:
- El motor no arrenca: Check fuel level, oil level, spark plug condition, and ensure the 4-in-1 switch is in the correct position (CHOKE for starting, then RUN).
- Sense potència de sortida: Check if circuit breakers have tripped (reset if necessary). Ensure devices are properly connected and not exceeding the generator's wattage capacitat.
- CO Watchdog Shutdown: If the CO Watchdog sensor activates, move the generator to a well-ventilated outdoor area. Allow it to cool down and clear any CO buildup before restarting.
- Sobrecàrrega: If the overload indicator light is on, disconnect some devices to reduce the load. Press the reset button on the control panel.
For more detailed troubleshooting, consult the full user manual or contact customer support.
