You are getting confused Big-All.

Look at the link that you first posted-
http://www.mtmc.co.uk/Spare-Parts/Dewal ... 18642.aspx

That is where the Brushes and brush caps are listed, not the second link you posted to the newer model

the dewalt 742/743 series saws use an induced field (induction) motor, the manual someone has posted is for a brush motor chopsaw.
heres what the professonals would check in the order they would check it.
1) plug, is it wred correctly and any loose parts
2) cable, check continuity from end to end down each core flexing lead whilst doing so.
3) switch, check that you have continuty thru it and that it is breaking the circuit (not made any easier by the fitment of a relay type)
4) start capacitor, is it charging? BE CAREFUL thats a large capacitor and can give you a fair old jolt
5) does the motor spin freely?
6) is there a peak start surge and even run current supplyed to motor?
if still you havnt fixed it you need to bring it to me or someone else in the repair trade.
