To engage the percussion mode, move the selector switch and that moves a plate with a hole on it. This movement aligns the hole with the second gear’s axis. The casing drops of a few fraction of an inch down onto the axis. The ridges at the back of the gear insert themselves into the ridges of the metallic plate above. Squeeze that trigger switch and the motor starts. That turns the first gear which turns the second gear. The ridges at the back of the second gear slide along the metallic plates ridges. This moves the casing away. That casing falls back violently pushed by the way of the drill operator. And it all happens over and over again.
