Hold the contact element and press the knob toward the
nose tip. While keeping the knob pressed, turn it
counterclockwise fully. Then release the knob and
remove the contact element from the driver guide. If you
have difficulty removing the contact element because it
is caught by the safety cover, open the magazine cap.
