Claim 5:
6. A method of using the drill rig of claim 1 in conjunction with a rod handler, wherein the drill rod connector comprises at least one male thread, the method comprising:
retracting the second head assembly toward the rear portion of the drill rig and away from a drill string to permit receipt of the first drill string component between the second head assembly and the drill string;
receiving the first drill string component from the rod handler so that the first drill string component is coaxial with the longitudinal drilling axis;
moving the second head assembly until the at least one male thread of the spindle engages at least one female thread of the first drill string component;
rotating, using the motor, the spindle to thereby threadedly couple the spindle to the first drill string component;
moving the second head assembly forward via the feed frame until the first drill string component engages the drill string; and
rotating, using the motor, the spindle to thereby threadedly couple the first drill string component to the drill string, thereby creating an extended drill string.
