There're two ways to adjust the limb alignment, bolt and block. 

For bolt adjustment, you can adjust your limb alignment to make it perfectly compatible to the riser simply by removing or adding the supplied washers to the alignment dowel. But in this adjusment way, you need to unstring your bow.

For Block adjustment, you can simply adjust the center-shot without unstringing the bow.You only need to twist the locating screws on the two side of limb pocket.
