4. To replace the Motor Carbon Brushes: It may become necessary at sometime
to replace the
two Carbon Brushes (49) when the Motor performance decreases,
or stops working completely. The Carbon Brushes are located on each side of
the Field Case (31). To do so, remove the two Brush Cap Covers (51). Next,
remove the two Brush Caps (50). Then, remove the two Carbon Brushes (49). If
the Carbon Brushes are worn down more than 1/2, replace
both Carbon Brushes.
If, however, the Carbon Brushes are just dirty they may be cleaned by rubbing
them with a pencil eraser. When installing the Carbon Brushes, make sure the
carbon portion of the Carbon Brushes contact the Motor Armature, and that the
springs face away from the Motor. Also, make sure the springs operate freely.
After cleaning or replacement, replace the Brush Caps (50) and Brush Cap
Covers (51).
NOTE: New Carbon Brushes tend to arc or spark when first
used until they wear and conform to the Motor’s Armature. (See Figure E.)
5. WARNING! All maintenance, service, and repairs not listed in this
