inserting, using the rod handler, an empty core tube assembly into the drill string;
moving, via the feed frame, the second head assembly toward the front portion of the drill rig until the overshot engages the empty core tube assembly;
disengaging the rod handler from the empty core tube assembly;
moving, via the feed frame, the second tube assembly toward the front of the drill rig to further insert the empty core head assembly into the drill string;
releasing, using the overshot releaser, the overshot from the empty core tube assembly;
moving, via the feed frame, the second head assembly toward the rear of the drill rig;
aligning, using the actuator, the spindle with the longitudinal drilling axis of the drill rig;
moving, via the feed frame, the second head assembly toward the front of the drill rig until the spindle engages the drill string; and
