Replacing.Brushes
This machine is equipped with a universal motor that
uses two carbon brushes to transmit electrical current
inside the motor. These brushes are considered to be
regular "wear items" or "consumables" that will need to be
replaced during the life of the motor. The frequency of
required replacement is related to how much the motor is
used and how hard it is pushed.
Replace both carbon brushes at the same time when the
motor no longer reaches full power, or when the brushes
measure less than
1
⁄
4
" long (new brushes are
5
⁄
8
" long).
