I recently had to replace my old Bosch 4000 saw. Decided to spring for the GTS1041A REAXX Saw. It's a great saw, but I seem to be having trouble getting good dust extraction with my shop vac attached to the dust port. The dust shroud's latch is in the closed position, per the manual instructions. The vacuum is the same one I used with my 4000-09 saw, and didn't have this problem. I also verified that the vacuum is working properly, independent of its use with the saw. Anyone out there seeing this issue with the REAXX?

Any help appreciated.
