are just dirty they may be cleaned by rubbing them with a pencil eraser. If

cleaning and replacing used brushes, try to install them in the same holders and

in the same direction they were removed. When installing the Carbon Brushes,

make sure the carbon portion of the Carbon Brushes contact the Motor’s Rotor

and that the springs face away from the Motor. Also, make sure the springs

operate freely. After replacement or cleaning, replace the two Brush Holder

Covers.

NOTE: New Carbon Brushes tend to arc or spark when first used until

they wear and conform to the Motor’s Rotor.
