I took a couple of photos. This is what mine looks like. I just put mine on the runner (which I made sure was clean and waxed) and then turned the allen screws until it ran smoothly. I think it was notchy when I started, but turning those screws fixed it. If it doesn't then I think you might have a duff table. You can buy all the bits from Charnwood (I did as I bought the saw second hand with no sliding table) but I think they are identical to the Axminster TS250 table. Good luck!
