The Way To Use: - First, insert the hose into the liquid which needs be extracted. Next, squeeze the rubber pump to remove the air inside,then use your fingers to block the outlet of the hose and release the rubber pump (please keep the arrow on the rubber pump down). After the pump is restored to its original state and the liquid is pumped up to fill the rubber pump, loosen the finger which is blocking the outlet.Repeat the operation 1-2 times to form a continuous flowing. Please keep the rubber pump as low as possible below the inlet position.
