You first released the lever and turned it 180 from the "unused" position, which opened the valve. After that, you turned it upside down and shook the extinguisher, to mix the chemicals in the extinguisher. They also made a similar foam extinguisher, which I think you had to turn it upside down and strike the head of it, so that it could start discharging.
