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 a screwdriver to remove the brush holder caps. Take 
out the worn carbon brushes, insert the new ones and 
secure the brush holder caps.
