6.2 VACUUM MOTOR SERVICING
During the life of the vacuum motor, the carbon brushes inside the motor may be replaced once. These brushes are
considered to be a ‘wear part’ and their replacement is not
covered under the vacuum warranty. For additional
information, please contact Superabrasive, or an authorized
service facility.
To replace any of the motors, first switch off the dust collector
from the power supply, then disconnect the power cord
coupling from the control board of the motor head.
To reach the motors for servicing, you must dismount the motor
head cover.
To replace, disconnect the power cord (pos.1 Fig.6.2) of the
driving unit (pos.3). Unscrew the two bolts (pos.2). Turn the
driving unit (pos.3) against its axle (pos.4).
Unscrew the 6 screws (pos.5,Fig 6.2) and take out the motor
base plate with the three motors and the power cord between
the board and the motor head.
