i am stuck just like you. i bought the DE 7492 in India. the table saw came without a blade. now, when i have to decide, which blade i need to buy, i am confused. available here are only 254 mm blades. these blades will touch the riving knife mechanism. also, i am not sure about the size of the table saw arbor shaft. the table saw has been delivered to my residence in another location, far away from my present residence. so, unless i go to where it has been delivered and actually measure the diameter of the arbor and the space available before the saw edge touches the riving knife mechanism, i will not be able to decide which blade to buy.
