Replacing Brushes
Your machine is equipped with a universal motor
that uses carbon brushes to transmit electri-
cal current inside the motor. These brushes
are considered to be regular "wear items" or
"consumables" that will eventually need to be
replaced. The frequency of this replacement is
directly related to how much the motor is used
and how hard it is pushed.
Replace the carbon brushes when the motor no lon-
ger reaches full power, or when the brushes mea-
sure less than
1
4" long (new brushes are
5
8" long).
