A telescoping arm with securable pole-tilt assembly for manipulating a utility pole and comprising a pair of opposed jaws and a saddle, the arm comprising a boom and an elongate pin for selectively securing the pole tilt assembly in an operating position to the end of a telescoping boom section or in an out of operation position to an intermediate boom section wherein in the out of operation position the telescoping boom section can extend through the pole-tilt assembly and the elongate pin engages the jaws of the pole-tilt assembly preventing them from being articulated downwards towards the saddle, thereby preventing damage to the telescoping boom.
