Hi.
I got a Titan circular saw from Screwfix a couple of years ago.
The brushes had worn down to the springs about a year ago. I had contacted Screwfix who then directed me to a spare parts supplier. I then bought a new set of brushes. I have since installed these.
Ever since then I've always had a lot more blue sparking from the commutator (visible through the ventilation vents). I put this down to the brushes bedding in from a flat surface to a curved one.
Now tonight, whilst cutting pallets, I now have yellow sparks coming from the other end of the motor.......
Is this something I should be concerned about? What is causing it? is it repairable or shall I need a new circular saw?
Stephen.
