Replacing BRUSH ASS’Y (4-33)
With the DA-98HR, the drum is grounded through the sliding
action of a slip ring and brush in place of through a single
contact point which is the case with previous DTRSs.
Therefore, when BRUSH ASS’Y (4-33) has been used for
the specified hours, its performance can no longer be guaran-
teed, eventually leading to fracture of the brush. To prevent
this, make sure to replace BRUSH ASS’Y when replacing
DRUM ASS’Y.
The replacement timing is about 1000 hours which is the
same as that of DRUM ASS’Y.
As the worn debris is accepted by COVER, BRUSH (4-45),
also be sure to remove the debris when replacing BRUSH
ASS’Y.

BRUSH ASS'Y(4-33)の交換について
DA-98HRのドラムアースは、従来のDTRSのような接点
式ではなく、スリップリングとブラシの摺動によって
います。従って、BRUSH ASS'Y(4-33)の使用時間が限
度を超えると磨耗により性能が保証できなくなり、最
終的には切断してしまいます。そこで、ドラムASS'Y
交換時には、必ずこのBRUSH ASS'Yの交換を行ってく
ださい。
交換周期は、ドラムASS'Y交換周期と同じ約1000時間
です。
また、磨耗粉をCOVER, BRUSH(4-45)で受けるように
なっていますので、BRUSH ASS'Y交換の際は磨耗粉の
除去も行ってください。
