endure.

The life time of the brush unit is 2,000 hours. The brush needs to be replaced if
1/2 of the overall length is worn.
The commuter needs to be kept clean. If any carbon power fixed on the com-
muter cannot be removed with a dry cloth, burnish it with a sand paper # 150 to
#400.
The carbon brush can be removed by removing the caps located on both sides of
the bottom portion of the motor.
