titan circular saw
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. |

New brushes take maybe five or ten minutes to bed in & then the sparking should reduce. If it doesn't, two things. Wrong grade of brushes. Armature is f****d so burning out your original brushes. You can check the armaure with and Ohmmeter. Often there is visible burning mark on one segment on the commutator. I expect they will want silly money for a new armature. |
