5-13-1) Functions of Thread Detector
Detection of the breaks of upper or lower threads prevents ill quality embroidery. The thread- break detector unit
contains rollers that sense the smooth feeding of the thread. Any dust, thread remnants, etc. will interfere the
rollers
’
rotation and may cause wrong detection.
5-13-2) Disassembling Thread Detector
You will need to disassemble the thread-break detector unit to clean. Remove the cover of the thread tension
adjusting plate, separate the cables and unfasten the roller base joint screw. The entire unit will be disassembled
including the rollers and bush bearing.
[CAUTION]
Make sure to correctly place the thread detecting roller to have the unit properly function. Check between
the sensor groove and the film. If needed, unfasten the board base screw to adjust the board.
