SERVICE
2.Place a straightedge on the outfeed table so it extends over the cutterhead. For best results, use a straight- edge that will stand on edge without having to be held in place, as illustrated in Figure 36.
3.Rotate the cutterhead under the straightedge.
—If the knives are parallel to the straightedge, rotating the cutterhead will move the straightedge slightly (1/8") forward; no adjustments are necessary.
—If the knives fall below the straightedge, or if the knives lift the straightedge and move it more than 1/8" when you rotate the cutterhead, the knives must be adjusted.
