Balde movement up and down? If so, that would suggest worn bearings in teh gearbox. If they are worn there then they might also be worn in the motor. If this happens the armature will float up and down causing it to rub against the stator. You may be able to get the bearings sorted without needing any new motr parts. I beleive this saw uses an induction motor so beware if it does need replcing you might want to be sitting down when you get the quote.

Hi. I have a dw744 and the motor started to sputter/vibrate and spark a lot. How doe I know if I need to replace the brushes?


Not Much on saws but it is alot like a starter motor and if the Brushes wear down it will cause metal to metal contact with the armeture and will cause them to spark and soon wont work.

The motor sometimes starts right away and at other times I have to use a wood stick to spin the blade and it starts


the brushes in a dw744 have a ledge when they get too short that hangs up. replace the brushes and you should have no problem. the brush holder comes right out with a little coaxing with a screwdriver after the end cap is removed. it just plugs right in.

I was cutting 2" dense foam insulation board,


The problem you have is a faulty field coil, the Bosch saws unfortunatly have a bit of an issue with this. The coil can be replaced separatly so you won't have to replace the whole motor. Bosch has a 1 yr warranty on thier table saw so this is a warranty replacment provided the saw was purchased within the year. If not the coil replacment is still cheaper than buying a whole new saw, but should really be done by a service center because of the level of difficulty of the repair.

How can i get a guard for this table saw the dw 746


You can order them at www.dewaltservicenet.com.
The DW746 and DW744 use the same guard assembly, if you're talking about the hinged guard over the blade.

Replaced armature and brush's and there is alot of heat and spark and it starts slowing down?


Unless somewhat preformed, brushes have a tendency to arc like crazy and can produce heat and even smoke. I would remove the brushes and use a fine 'keyhole' type file to give them a little inside curve so they have better contact to start with.
