BRUSH REPLACEMENT INSTRUCTIONS

1. Brushes that are worn out, or oil-soaked, should be replaced.




2. When replacing field coil brushes, crush worn out brushes with pliers, taking care not to damage the pigtail.
3. Sand the pigtail end with sandpaper to ensure good soldering.
4. Insert the pigtail into the hole provided in the new brush and solder it. Make sure that the pigtail and excess solder do not come out onto the brush surface.




5. When replacing the ground brush, slide the brush from the brush holder by prying the retaining spring back.
