Taking the edge off the brushes as per my drawing will also decrease the current the motor will draw. Spring pressure on both brushes should be about the same. If you don't have a way to check the tension, you should try to put in a new set if possible. Guido. [Reply]   [No Email]

I have not done much repair in this type of thing for years but did a whole lot if it back when I worked at tracker marine so not new to this just been a few years as in well I left there in 1992 so yep a few to many maybe   [Reply]  [No Email]

Taking the edges off the brushes will do two things: decrease the amp draw, and increase the tool's R.P.M's. Lighter springs will do the same thing. Guido.   [Reply]  [No Email]
