5-12) ASSEMBLY AND FUNCTIONS OF THREAD DETECTOR

5-12-1) 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 rotation of the thread. Any dust, thread remnants, etc. will interfere with the
rollers' rotation and make wrong detection.

5-12-2) 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 place the thread detecting board in the correct position, or the unit will not operate - check between the
sensor groove and the film. If needed, unfasten the board base screw to adjust the board.
