Auto Thread Cut Key
When the machine has stopped sewing, press this key to cut the needle and bobbin threads. (The LED signal
blinks during auto thread cutting.)
CAUTION: Use the thread cutter on the face plate for threads heavier than 30 wt. or decorative
threads.
Clean the auto thread cut mechanism regularly. See page 166.
After auto thread cutting, pull the needle and bobbin threads up and back under the foot.
Auto thread cutting is not recommended when a thread spool is almost empty, as thread will not unwind
smoothly, causing the thread to bunch or slip.
