The specific operation steps are as follows:

1, find the tanker card slot, insert the fuel card into the slot, and hear a click, indicating that the card has been inserted in place.

2, then there will be a language prompt, enter the password, enter the password and then choose the refueling method, quota or fixed number.

3. Lift the oil gun, insert it into the tank mouth, grab the refueling trigger and jam the bayonet, and start refueling. When it is full, the gun will jump automatically.

4. After refueling, put the oil gun back in its original position, then cover the oil tank cover, take back the fuel card from the tanker, and complete the self-service refueling.
