I have the same sliding table on a K500 and you cannot if you plan to clamp on both ends. With clamp, the minium is 2800mm to cut 8 ft board,?if your clamp bases are not too big. According to many threads about it on this forum.
The infeed end of this sliding table is an additional 12 inches or so that is useless from my point of view. Check the K940 layout in the file section and look for the design of the handle of the 2500 sliding table. Or look in their pdf catalogue page 57.
Here is the picture: to cut to full length you need your wood to be on that additional aluminum extension. I hope I make it clear.
