Replacing the Motor Brushes
It may become necessary at sometime to replace the motor brushes when the motor perfor-
mance decreases, or stops working completely. The following steps describe their replace-
ment. This procedure should be done by a qualified technician.
1. Unplug the Power Cord Plug from the electrical outlet.
2. Remove the Brush Holder Caps (14) and Carbon Brushes (13) from the Motor
Housing (16).
Examine the Carbon Brushes. If the they are worn past 3/16 inch in length, or if the
spring or shunt wires are burnt, they must be replaced. Never replace just one brush. If
the brushes are only dirty, and not worn down, you can use a pencil eraser to clean
the brush tips.
