Replacing Motor Brushes - Grizzly T32720 Owner's Manual

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

If your machine is used frequently, we recom-
mend keeping an extra set of these replacement
brushes on-hand to avoid any downtime.
