some time ago I bought this saw a 254 mm table saw model no FMTC1500Tk from B & Q. I had not used it much until recently when it was used quite a lot and I decided to change the blade, the instuction book said put spanner on the blade bolt and another one to hold the spindle fast, but there is no where to hold the spindle only the one nut behind which is a washer then thesaw blade. I went to my local B & Q but they stopped sellig these saw's some time ago and no one had any idea . Has any one any experienced this problem ?. hope to hear some good news as the old blade is getting blunt now. Thanks in advance.
