Yep, first thing I did on my Ex21 was remove the shroud. I keep a fan behind me on the floor, one mounted to the wall on my left, and one in the window of my shop, and I wear a dust mask. I clean up with a shop vac every day after scrolling. I tried using vacs on my saw, but, the noise drove me insane and the dust removal was very minimal.
