Question about Porter Cable 345 6" Circular Saw Saw Boss
My Porter Cable SAW BOSS 6" panel saw seemed to be working OK until recently it started running as if it lacked power under even a slight load. I pulled the carbon brushes and noticed they were worn extensively, and even chipped/broken off, on one side of each rectangular carbon brush, while the other side of the brush appeared normal and intact. Inspecting the problem further revealed one segment of the commutator having much, much more carbon buildup than the other segments. I also noticed that the small copper section (triangular piece at the top of each individual segment of commutator) on the troubled segment had somehow gotten pushed up and was therefore WAY OUT of line with all of its neighbors. Upon attempting to gently bring said problem part back down and into line with all its buddies it (not surprisingly) snapped off. Can anyone tell me what I need to do, over and above replacing the carbon brushes, in order to get my saw running normally again? The saw doesn't have many hours on it at all, although it is pretty old I haven't used it much over the years, BUT when I do need a lightweight panel saw for certain jobs I do, the unit is indespensible. Please help thank you.
You will have to change the carbon brushes of your Saw boss. Secondly, you must also check the condenser with the help of a Multimeter to check whether there is a proper uniform flow of the voltage in the unit or not.
Let me know for any other further assistance.
