I am disappointed that the dust collection system that is a big deal according to Dewalt will not fit on the sander if it is on the frame. This was not disclosed by Dewalt in anything I reviewed before I purchased it. This is just bad engineering. The instructions with the frame acknowledge the fact and tell you to turn off the dust collection lever when it is on the frame. So they knew of the problem. Why didn't they just design the frame to work with the dust collection system?
