Operating Instructions
Fuel Transfer Process
- Ensure the pump is securely attached to the fuel can and the suction pipe is fully submerged in the liquid.
- Insert the discharge nozzle into the receiving tank (e.g., vehicle fuel tank, lawnmower). The nozzle includes a clip to secure it in place.
- Press the "ON" button on the pump unit. The built-in LED indicator will illuminate, and the pump will begin transferring liquid.
- Monitor the transfer process. The auto-stop sensor in the nozzle will automatically shut off the pump when the receiving tank is full, preventing overfilling and spills.
- Once the transfer is complete and the pump has stopped, press the "OFF" button.
- Carefully remove the discharge nozzle from the receiving tank, allowing any residual liquid in the hose to drain back into the fuel can.
- Remove the pump unit from the fuel can.
