Inportant:
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 tan 3/8" (9.5mm)
long.
