4. Konfigurazioa
Lehenengo aldiz erabili aurretik, jarraitu konfigurazio-urrats hauek:
- Despaketatzea: Kontu handiz atera sorgailua bere paketetik. Begiratu bidalketa-kalterik dagoen.
- Gehitu motorraren olioa:
- Aurkitu olio-betetzeko tapoia/maila-varilla.
- Add the recommended type and amount of engine oil (refer to specifications for oil type and capacity). Do not overfill.
- The oil warning indicator will prevent starting if the oil level is too low.
- Gehitu erregaia:
- Ziurtatu sorgailua itzalita eta hoztuta dagoela.
- Open the fuel cap and carefully fill the fuel tank with unleaded gasoline. Do not overfill.
- Itxi ondo erregaiaren tapoia.
- Kokalekua: Place the generator on a firm, level surface outdoors, away from windows, doors, and vents to prevent exhaust fumes from entering enclosed areas. Ensure adequate clearance around the generator for ventilation.
5. Funtzionamendu-argibideak
5.1 Sorgailua abiaraztea
- Ziurtatu sorgailua gainazal mailakatu batean dagoela eta konexio guztiak ondo lotuta daudela.
- Turn the fuel valve to the "ON" position (if applicable).
- Move the Run/Off/Choke switch to the "CHOKE" position (for cold starts).
- Atzerakada-abiarazlearen heldulekua irmo eta leunki tira motorra martxan jarri arte.
- Once the engine starts, gradually move the Run/Off/Choke switch to the "RUN" position.

Figure 7: Easy Starting. This image shows a hand pulling the recoil starter cord, demonstrating the simple starting mechanism.
5.2 Gailuak konektatzea
- Allow the generator to warm up for a few minutes before connecting appliances.
