1 - Make sure that the plate is cut squarely on the end toward the
feed table (henceforth, forward end).
2 - Position the forward end of the base at exactly the position of
the forward end of the plate. (Because you can adjust the paper

4 - Place the lead rule against the forward end of the base and lock
