VACUUM MOTOR CARBON BRUSHES
REPLACEMENT
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"
