Hesitating too long at

relationship
Damage or “Burr” at
needle hole of throat
plate or other thread
handling part.
Wrong type of needle
Other possible
problems:
• Move more quickly so stitches don’t overlap or build up. When
starting the machine, begin moving immediately. Sewing in one
place too long will cause the thread to break or nest.
• Timing-consult a repair technician.
• If thread is shredding at the throat plate, check for burrs or jagged
edges. Gently rub with metal cloth to remove the sharp edge. Consult
a repair technician to polish any hard to reach or delicate areas, or if
the burr is inside the throat.
• Use needles recommended by Baby Lock. Using the wrong needle
with a smaller shank diameter causes many problems.
•Needle too close to hook, causing friction and possible collision of
hook point and needle, (broken thread).
• Needle plate damage. Hook damage.
• Broken needles or damaged needle bar clamp.
• Check the communication cables that connect the handlebars to
the casing of the machine to make sure they are secure.
* If the troubleshooting above does not eliminate the problem, please
consult your authorized Baby Lock Crown Jewel retailer.
