Step 2

              Assemble
  • Insert carbon brushes with the springs. The alignment of the brushes must match the alignment of the axis! The brushes must be able to smoothly move along the guide.
  • While applying pressure to the springs, check whether the brushes are in contact with the rotor by slowly turning the shaft.
  • Screw the blue cover cap back on.
