I have had my MB9020 for a while now and would like to add a couple of things which I found:
I set it all up and used it for a while, everything fine. Then started getting quite a bit of snipe, whatever I did. I have been reliably informed this is an outfeed table mal-adjustment, but the MB9020 has no outfeed table adjustment!
So I took the whole thing apart, put a heavy straight edge on both tables and put it all back together again, tightening all nuts and screws lots. I took the blades out, re-aligned them both twice with the setting tool and it is now brilliant!!
Great little machine especially for the money!
