I have the Sheppach model, which is the same saw, I believe. the tracks are identical because I connect them to cut full lengths of plywood.
It seems to work OK for me. There is a little sawdust that escapes but I suck it up after each cut. My shop vac connects to the dust port with no problems.
I have seen a video on You Tube about hacks to make the saw track better and eliminate the dust spillage, but I forgot where it is and haven't tried any fixes.
Just finished breaking down 8 sheets of plywood using this method to cut up the big pieces into manageable sizes so I can rip them on the table saw.
Hope this helps.
That's my story and I'm stickin' to it!
