description A method includes receiving a user input to conduct a coarse pivot movement of a drill mast. A locking-pin withdraw signal is sent to a locking pin actuator for a first period of time. Responsive to determining that a locking pin is engaged with a locking hole after the first period of time, the drill mast is repositioned from a current angle to an initial angle. A second locking-pin withdraw signal is sent to the locking pin actuator for a second period of time. Responsive to determining that the locking pin is engaged with the locking hole after the second period of time, the drill mast is repositioned between a minimum drill mast angle and a maximum drill mast angle and sending a third locking-pin withdraw signal to the locking pin actuator for a third period of time.
