CHECKING CARBON BRUSH
Brush Maintenance Essentials
(Effective Length)
The brush is the area which touches the slip ring, and
its surface must be kept smooth.
If it is not smooth then carbon and other substances
will adhere between the brush and slip ring.
This must be buffed with sandpaper or the like
because it is hazardous.
The usable length of the brush is 5~11mm, so if the
brush is 5mm long or less replace it with a new one.
