"The secondary chamber can be pumped up to pressure, enabling a stainless steel foot-lever to release the compressed air in an immediate, continuous discharge, quickly and easily seating the [tubeless] tire bead.

Note: When using the Digital Pressure Overdrive as a regular pump, you must fill the air chamber before air will begin to flow into empty tire/tube. When topping off a tire/tube that already has pressure in it, the chamber will have to reach the same pressure the tire/tube is at first before it will begin to inflate it further."
