Configuració inicial
Follow these steps to prepare the generator for its first use:
1. Wheel and Foot Assembly
The generator comes with wheels and support feet that need to be assembled for easy transport and stability.
Demonstration video on assembling the wheels and support feet of the generator. This video shows how to securely attach the wheels and supports to ensure the unit's mobility and stability.
2. Afegir oli de motor
Before the first start-up, it is crucial to add engine oil. Use SAE 10W-30 engine oil. The oil capacity is 0.6 liters.
- Unscrew the oil cap/dipstick.
- Use a funnel to slowly pour oil into the reservoir until the level indicated on the dipstick is reached (do not exceed the "H" position).
- Screw the oil cap back on securely.
Video illustrating the procedure for adding engine oil to the generator. It shows how to unscrew the dipstick, pour the oil, and check the correct level.
3. Afegir combustible
Add unleaded gasoline to the fuel tank. The tank capacity is 18 liters.
- Assegureu-vos que el motor estigui apagat i fred.
- Obriu el tap del dipòsit de combustible.
- Slowly pour gasoline into the tank, avoiding overfilling.
