This jointer 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 "consum-
ables" that will need to be replaced during the life
of the motor. The frequency of required replace-
ment is often related to how much the motor is
used and how hard it is pushed.
If your machine is used frequently, we recom-
mend keeping an extra set of these replacement
brushes on-hand to avoid any downtime.
