I just put my AC9944 stand together along with my Dewalt DW715 saw. My question is that on the brackets, the holes on the saw line up with the sliding holders for the carriage bolts. However, the saw base isn't as deep as the bracket is, so once it's all bolted together and the brackets are on the stand, I can scoot the entire saw back and forth - there's about 4 inches play. Is this normal? Let me know if this is a very confusing question. Just to be clear, the brackets don't move and the bolts are tight, I can just move the entire saw base since the sliding holders aren't at the farthest points on the brackets.
