To adjust lateral run-out, adding tension to a nipple on the right will pull the rim right, and vice versa. For radial run out, tensioning a group of spokes at a high point in the rim will pull that area of the rim towards the hub. The adjustable jaws of the jig are used as a gauge. However, the jaws are not symmetrically accurate enough to set dish. For that reason, many wheel builders remove or tie back one side.
