I just purchased the R4121 12" dual bevel mitre saw. I'm trying to figure out how to adjust the height of the movable portion of the mitre table. The movable portion of the mitre table is slightly higher than the fixed portion of the mitre table. Can you adjust the table to make it flush? Not a big deal yet, but moulding hangs up when you slide it accross the table. Also may throw off precise cuts a bit.
