in a counterclockwise direction (see arrow). The rotation of the loader motor
gear causes the leader pin block to move into the cartridge and disengage the
leader pin. As you rotate the screwdriver, the allen wrench moves slightly.
3. Continue to rotate the screwdriver until you feel no resistance to the allen
wrench (you may have to rotate the screwdriver for a lengthy period). When
the wrench moves freely, the leader pin has disengaged from the leader block.
Remove the allen wrench.
