Common Adjustments - Thread Breaks
Always inspect needle position and determine if actual thread break has occurred. If no thread break is ap-
parent, check all the thread paths. Then do a manual trim and check the bobbin supply. If thread has broken,
follow the correct thread path and rethread the needle.
TO RESUME STITCHING AT THE APPROPRIATE SPOT IN THE DESIGN:
• Trim (Scissor Key) back up using your stop key and then start again.
PREVENTING THREAD BREAKS
• Remember to store thread properly since aged and improperly stored thread can cause thread breaks.
• Thread will become brittle due to prolonged exposure to air, light, heat and age. Replace the old thread and
store new thread in a dark, cool place.
• When re-threading the machine make sure that the thread goes through all the guides and in the proper
order.
• Make sure that the tension is correct. Loose tension causes thread to pile up and loop, and tight tension
causes pulling, puckering and thread stress.
• Too many stitches in a small area and/or heavy densities can cause thread breaks. Try deleting short
stitches or increasing the design by 5-10%.
• Do
NOT use tape to tie off thread ends, since tape leave a stick residue that causes friction and breaks.
• Check for burrs in the thread guides, needle eye, thread plate and hook.
• Make sure that the needle is pushed in all the way when cleaning needles.
• Replace bent or damaged needles.
• Excessive backing will apply greater friction to the needle and the thread.
Thread Breaks
Typical Causes
Appearance
Solution
Too much or tool little tension or
poor quality thread.
A small tuft of fiber on the end of
the broken thread.
Loosen tension, change brand of
thread, try a new cone of thread
Improper placement of stitch
relative to previous stitch. Stitch
penetrates and splits previous
thread.
Broken end will have a bend in the
thread and a tuft on the end.
Edit stitch placement or re-digitize
the design.
Thread is cut by a sharp edge on
the rotary hook.
Thread will have a clean cut.
Polish or replace the rotary hook.
Hook point catches only a portion
of the thread.
Thread will fray and break.
Adjust timing of the rotary hook,
use correct needle size, try a
larger needle.
Obstruction in the thread path.
Make sure thread pulls smooth
through thread path.
Needle damage or improper
needle insertion.
Replace needle or insert needle
with scarf on the back.
Tight density
Fraying
Reduce stitch density or make
more than one pass using multiple
layers of stitching with lighter
density per layer.
Descending needle point pen-
etrating or catching thread.
Adjust take up spring so it is
working until the eye of the needle
penetrates the fabric or adjust the
tension.
