Probable Cause
Remedy
Cut the entangled thread and remove it from the
race.
Use the presser foot locking pin (black button
on the left side) on zigzag foot "J" to keep the
presser foot level while sewing.
Adjust presser foot pressure within the settings
screen.
Contact your authorized Baby Lock retailer.
Firmly tighten the needle clamp screw. If the
needle is bent or blunt, replace it with a new
one.
Replace the needle.
Lift up the fabric and cut the threads below it,
and clean the race.
Turn off the machine, and remove the needle
plate. If the needle that fell into the machine can
be seen, use tweezers to remove it. After
removing the needle, return the needle plate to
its original position and insert a new needle.
Before turning on the machine, slowly turn the
handwheel toward you to check that it turns
smoothly and that the new needle enters
through the center of the needle plate opening.
If the handwheel does not turn smoothly or the
needle that fell into the machine cannot be
removed, consult your authorized Baby Lock
retailer.
Remove the tangled thread from the bobbin
case. Re-install the bobbin case so it is
correctly positioned.
Remedy
Check the steps for threading the machine and
rethread the machine.
Reset the bobbin. (If needle plate was removed,
reinstall needle plate and tighten screws prior to
installing bobbin case. Check to make sure
needle enter through the center of needle plate
opening.)
Check the "Fabric/thread/needle combinations"
chart.
Reattach the presser foot holder correctly.
Adjust the thread tension.
Use a correctly wound bobbin.
Replace the needle.
Incorrect bobbins will not work properly. Only
use a bobbin designed specifically for this
machine.
