Changing the Motor Brushes

The motor brushes wear out over time and need to be replaced by an authorized service center. Festool does not condone brush replacement by the end-user. Completion of this procedure by an unauthorized service center will void the tool's warranty.

The motor brushes are graphite bars that provide an electrical connection between the motor controller and the rotating armature. When the brushes have worn past their useful length, spring loaded wear pins are exposed that separate the brush from the armature contacts. This disables the motor to prevent damage. For a shorter break-in period without excessive arcing, new brushes have ribs that quickly form to the curve of the armature.

Procedure

CAUTION! Make sure the power cord is unplugged before beginning this procedure.

1.Remove the four screws that secure the access cover to the motor, and remove the cover.

2.Lift the wire connectors off the terminals on the brushes.

3.Remove the screw that secures each brush to the motor housing. Be careful not to drop the screws into the motor.

4.Carefully lift the brushes up to remove them.

5.Insert the new brushes into the motor, and reassemble the saw by reversing the previous steps.
