I have a TS250-2 and found that the extractor tube that connects the lower blade outlet to the main outlet has a huge kink in it meaning the dust can't get through effectively ( or at all?). I phoned Axminster and they said a batch of the saws were fitted with very stiff hoses and this is probably the cause of the problem. They will send me a metre length of more flexible hose that I can fit myself and cut to size etc, so I'll see how that goes. Very happy with the saw other than that, though.
