4.2 Priprava goriva in olja
POMEMBNO: The pump is shipped without engine oil or gasoline. You MUST add engine oil before the first start-up. Failure to do so will cause severe engine damage and void the warranty.
- Dodajte motorno olje: Locate the oil filler cap/dipstick on the engine. Fill with appropriate 4-stroke engine oil (refer to engine manual for specific type and quantity, typically SAE 10W-30 or 10W-40). Do not overfill.
- Dodajte bencin: Rezervoar za gorivo napolnite s svežim, neosvinčenim bencinom. Ne prepolnite. Prepričajte se, da je pokrovček rezervoarja za gorivo varno privit.
4.3 Priključki cevi
- Sesalna cev: Connect a reinforced suction hose (minimum 80mm / 3 inches diameter) to the pump's inlet. Ensure an airtight seal to prevent air leaks, which can reduce pumping efficiency. Use the provided clamps.
- Izpustna cev: Connect a discharge hose (minimum 80mm / 3 inches diameter) to the pump's outlet. Secure with clamps.
- Nožni ventil/cedilo: Attach the included foot valve/strainer to the end of the suction hose to prevent debris from entering the pump and to maintain prime.
