Question about Dewalt Saws
How do i change the direction of rotation of the saw blade
All electric motors are set up in the same way. (Please refer to the little schematic I have drawn below.) Different models are wired slightly different and please note that your particular saw may only be able to go in one direction. Also some fields have 4 wires instead of 2, and if this is your case please ignore the rest of this post and bring your saw to a professional to be looked at. If your saw is going the wrong way your motor may be damaged and will need to be replaced or at least tested with the proper equipment. With that said, there should be 2 wires coming from your field. Wires "B" and "C" respectively. One of these should go to your switch, and the other should go to one of the brushes. Wires "A" and "D" are coming from your brushes and as noted above one should be going to the field. Let's assume that wire "A" is directly hooked up to the white wire of the cord. And let's also assume the the black is hooked up to "C" of the field. "B" and "D" should be linked in this setup. In order to reverse the polarity of the motor you would switch the field brush setup. One field wire and brush wire should always be connected to complete the circuit. By changing the "B"-"D" connection to instead be a "C"-"D" connection with "A" still going to the neutral "white" wire and now the "B" wire going to the switch, you have effectively changed the polarity of the motor. ****Please note that some of these saws have an electric brake and should not be rewired in this manner**** Again if your saw just started going the wrong way one day, you should get it looked at by a professional repairer. There may be more problems that have caused this to happen,
