Some oil pumps have the functions of forward rotation and reverse rotation. You can press
the reverse button to reverse the oil pump to fill the transformer.
If the oil pump has no reverse function, adjust the positive and negative poles of the power
supply line, start the oil pump, the oil pump will rotate in reverse direction to fill the
transformer with the oil.
If the battery is insufficient, start the vehicle when the oil pump is started, keep the engine
running.
1. During oil injection, if the oil pump temperature is too high, shut down and pause for
cooling for a period of time. When shut down, close the oil storage bag valve
synchronously.
2. In the late stage of oil injection, fold the oil storage bag to allow the oil to flow to the
flange.
3. When the oil filling is nearly completed, lift the capsule and try to fill the oil in the oil
storage bag into the transformer.
