I don't mean to sound too patronising, but I get all sorts coming into my repair shop. Have you checked the continuity up to the switch, i.e through the plug and cable? Also, remove the brush caps but leave the brushes in place and check the continuity across the back of the brushes. There should be a circuit cross the motor, and if there isn't it is probably just that the brushes are sticking slightly due to sawdust. If this is ok, then remove the brushes and check continuity from the live wire (with the switch locked on) to one brush holder and then the other. You should only get a circuit too ne holder. The do the same with the neutral side. Again you should only get continuity to one holder (the opposite one to the licve circuit). If you don't get continuity both ways, and the switch is new, this would indicate an open circuit/loose connection on the field coil assembly. If the armature was faulty the machine would normally still run but with low power and excessive sparking.

Great!! Could you please rate my solution as a "problem solved"?
I would greatly appreciate it.

you can try spraying some lubricant on the bolt/roll pin and see if that frees it up that is about all i used to do to them
SOURCE: how do you remove the
Just remove the brush caps. You may need to use a small pick or needle to pop the brushes out. In this diagram reference number 14 is the brush cap. They are just like a screw so you need to turn them to the left (counter clockwise) to remove them.
