4. Setup
Usati watanga kushandisa, ita matanho ekugadzirisa anotevera:
- Kuburitsa: Carefully remove the generator from its packaging. Inspect for any shipping damage.
- Wedzera Injini Mafuta:
- Tsvaga chivharo/dipstick yekuzadza mafuta.
- 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.
- Wedzera Mafuta:
- Iva nechokwadi chekuti jenareta yadzima uye inotonhorera.
- Open the fuel cap and carefully fill the fuel tank with unleaded gasoline. Do not overfill.
- Vhara zvakasimba chivharo chemafuta.
- Positioning: 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.
