Carbon  
Brushes  
If armature commutator is grooved, extremely pitted or not 
concentric, the motor will need to be replaced or sent to a 
qualified service center. 
Important: 
These brushes wear quicker as the length shortens due to 
increased heat. Spring inside brush housing will damage 
motor if brushes are allowed to wear away completely. 
Periodically check the length of the carbon brushes. Replace 
both carbon brushes when either is less than 3/8" (9.5mm) 
long.
