2. Configurare și instalare

2.1 Dezambalarea și asamblarea

Carefully remove all components from the packaging. Ensure all parts listed in the accessories section are present. The package includes a 25 ft outlet hose, inlet metal filter screen, spark plug socket, force rod, wrench pressure cap, pipe joints, sealing rings, and shock pads. Note: PVC suction hose is not included and should be purchased separately if required.

2.2 Installing the Vibration-Damping Base

Install the pump's vibration-damping base to ensure stability during operation. Use the provided wrench to secure the base.

2.3 Adăugarea uleiului de motor

Unscrew the oil dipstick and add engine oil. The required amount is 0.5 liters (600 mL). Check the oil level using the dipstick; the oil level should be between the 'H' (maximum) and 'L' (minimum) marks. Insufficient oil will prevent the pump from starting and may damage the engine. Change the oil after the first 20 hours of operation or one month, and then every 50 hours thereafter.

2.4 Umplerea rezervorului de combustibil

Fill the fuel tank with unleaded gasoline. The tank capacity is 3 liters. Ensure the fuel cap is securely tightened after filling.

2.5 Installing the Outlet Hose

Connect the provided 25 ft outlet hose to the pump's outlet. Place the sealing gasket flat onto the pump connector, then connect the hose and ensure it is securely fastened with the hose clamp. Strângeți furtunul clamp securely using the nut wrench.

2.6 Installing the Inlet Hose

Install the filter screen onto the inlet hose (to prevent large debris from being sucked in and damaging the pump). Connect the inlet hose to the pump's inlet. Place the sealing gasket flat onto the pump connector and ensure it is securely locked. The inlet hose must be a plastic hose, not a fabric-reinforced hose, for the water inlet connection. Ensure the clamp is fully tightened. A loose clamp will cause air leaks and prevent the pump from priming. The maximum suction lift for this pump is 7 meters. Exceeding this vertical distance will prevent the pump from drawing water.

2.7 Amorsarea pompei

Unscrew the priming port cap on the top of the pump. Fill the pump body completely with water until water flows out from the water outlet. This indicates the pump is full. Insufficient priming water will result in the pump's inability to draw water. Observe the water level and then tighten the priming port cap.
