5-4) LAMP ON THREAD TENSION ADJUSTMENT BOARD

1) Switch
① For normal operation, turn the toggle switch on to turn on the indicator lamp.
② If the machine stopped after detecting a thread break, move the frame back to the location of the thread break
using STOP button and restart the machine to pick up stitching (design edit).
※ If you want to move the frame back for any reason when a thread break has NOT occurred, press the toggle
twice.
[ CAUTION 1 ]
The take-up lever continues to operate even when the head is turned off. This movement can cause the upper
thread to come out of the holder. Use a rubber magnet to fix the unused upper thread onto the cover.
2) Thread Break Detector Lamp
Lamp on the head will blink when a thread break is detected, causing the machine to stop. You cannot turn the
lamp on or off using the toggle switch.
[ CAUTION 2 ]
Foreign substances around the thread detector roller may block smooth rotation of the roller and cause wrong
detection of thread break.
