SUBJECT

Prevention of Screw Loosening ( for Fur Brush Unit Cover)

MODEL

CATEGORY

To improve the reliability

UB710081~

CONTENT

The fixing screw of the fur brush unit cover becomes removed because of the vibration of the drive of the fur brush roller. This means that the screw may fall into the fur brush roller unit or its drive gear and this can cause poor rotation of the fur brush roller. The result is that the feed motor (M15) within the drive motor may suffer too much load causing abnormal rotation (C0001) or even damage to the gears in the vicinity of the feed motor.
