The control admits air to the pump as the gun is triggered, and shuts off and exhausts air from the pump as the gun trigger is released. With the pump’s relax-a-valve in the automatic position (see separate pump instruction manual), the exhausting air opens the relax-a-valve, permitting material to discharge through the drain back tube until pressure in the hose and pump is relieved.
