1. Unscrew the Brush Covers on the front and back of the machine using a flat head screwdriver (sold separately).

2. Pull the Brush out, noting the orientation of the old Carbon Brushes to prevent needless wear if they will be reinstalled.

3. The Carbon Brushes are approximately 5/8” long. If either one is worn down by more than 1/2, replace both Brushes.

4. To clean old Carbon Brushes, rub the contact areas with a pencil eraser.

5. Carefully, without forcing them, insert the Carbon Brushes. Make sure the carbon portions of the brushes contact the motor armature and that the springs operate freely. If reinserting a used brush make sure it is in the same orientation to reduce wear.

6. Replace the Brush Covers.
