The movement of the grip assembly is limited such that a minimum tubing gap between the rollers is equal to approximately twice a wall thickness of the tubing. The rollers are moved along the tubing to clear obstructions. The apparatus can also include a clamp assembly having one or more plates that limits movement of the grip assembly to bring the rollers no closer than the minimum tubing gap. Alternately, the grip assembly can include first and second shell halves movable between open and closed positions with a channel defined therebetween, and the rollers are mounted in the grip assembly.
