1. This unit uses expendable Carbon Brushes (#24). They need to be regularly inspected and
changed if necessary. The Carbon Brushes (#24) will wear down to the limit line, needing
replacement. Make sure the Carbon Brushes (#24) are always clean. They must be clean so
that they easily slide into the Carbon Brush holder (#25). Use an old toothbrush to remove
dirt or debris. See Figure 5 and the Assembly Diagram on page 9 of this manual.
