When the resin insulating tip inside the carbon brush is exposed to contact the
commutator, it will automatically shut off the motor. When this occurs, both
carbon brushes should be replaced. Keep the carbon brushes clean and free
to slip in the holders. Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use the HEX Spanner to take out iron button. Take out the worn carbon
brushes , insert the new ones and secure the brush holder cap. See below
picture.
