A pivot drive, a pivot, a cutter drive, a cutting head, and a camera are mounted to a base, and a remote control system operates the pivot drive to pivot the cutter drive from a stored to a use position, operates the cutter drive to rotationally drive the cutting head, and operates the camera to provide images of the cutting head used to cut out blockages at lateral connections of relined pipes. The camera and the cutting head are positioned in a spaced apart relationship facing each other, with the base extending beyond the cutting head sufficiently to provide this spacing. Optionally, the camera is mounted to a trailing portion of the base and the cutter drive is mounted to a leading portion, with control lines for the pivot and cutter drives routed back past but retained separated from the cutting head to avoid damage. |

1. A cutter for use with a cutting head that is operable to reinstate lateral pipes of a main pipe and a camera that captures images of the cutting head in operation, the cutter comprising:
an elongate base defining a longitudinal axis and receivable in the main pipe; a cutter drive that is operable to drive the cutting head and that is pivotal between a stored position generally inline with the base and a use position generally pivoted relative to the base; and a pivot drive that is mounted to the base and that is operable between a stored position in which the cutter drive is in the cutter stored position and a use position in which the cutter drive is in the cutter use position,wherein when the cutter drive is in the cutter stored position, the attached thereto cutting head and the camera are positioned in series along the longitudinal axis of the base, with a cutting tip of the cutting head and a lens of the camera facing each other with a fixed gap therebetween, wherein the cutter is operable to reinstate the laterals from a single access location without separate access locations for the cutter and the camera.
