Instructions for use:
* The correct way to use the suction pump is to stretch a tube into the liquid you need to pump, and first force it
* Squeeze the flat rubber ball to expel the air, then immediately block the outlet of the tube with your thumb, release the
rubber ball, etc.
* The ball slowly swells and recovers. After the liquid is pumped up to fill the rubber ball, the thumb blocking the outlet is
loosened. Repeated operation 1-2 times will form a continuous self-flow.
* This oil pump needs to rely on the pressure of air to achieve self-flow, because the inner diameter of the pipe is small and
the flow rate is relatively slow.
* Directions are used from top to bottom. When using, keep the position of the rubber ball as low as possible.
