You MIGHT find plans on the net on how to improve it's collection, if
this is not an unusual new saw design. Seems to me the trick is to seal
up any area besides the throat plate where air can leak into the
cabinet and defeat the DC. Also, I find when I use a zero clearance
plate, most of the time, more dust is thrown upward, necesitating dust
collection at the blade guard. There are several sites that cover plans
for good blade guards that incorporate dust collection, and are easy to
swing out of the way.
