Circular saw Start SPC-2200 Brought to my workshop because the brushes spark very strongly, there is a fire. When disassembling the saw, it turned out that due to bad bearings and their backlash, the rotor rubbed against the stator. I changed the bearings, rang the rotor and stator, but the sparking did not disappear. I show all the most interesting things in the video! Why the rotor sparks, the brushes spark, the collector sparks, the collector motor sparks strongly, the collector pulls the arc, the circular saw sparks on the brushes, how to repair a circular saw, replacing brushes, replacing bearings, how to choose a circular saw, review of the Start tool, the Start circular saw, the circular saw does not saw, disassembling the circular saw. #repairofpowertools #repair #circularsaw #brushesspark
