Fabric is Caught in the Machine and Cannot
Be Removed
If the fabric is caught in the machine and cannot be removed,
the thread may have become tangled under the needle plate.
Follow the procedure described below to remove the fabric
from the machine. If the operation cannot be completed
according to the procedure, instead of attempting to complete
it forcefully, contact your nearest Baby Lock retailer.

Removing the Fabric From the Machine

Immediately stop the machine.
b
Turn off the machine.

Remove the needle.
If the needle is lowered into the fabric, turn the
handwheel away from you (clockwise) to raise the
needle out of the fabric, and then remove the needle.

Remove the presser foot.
If the thread is entangled on the presser foot, remove the
entangled thread, and then raise the presser foot lever to
remove the presser foot. Otherwise, the presser foot may
be damaged.

c
Slowly turn the handwheel toward you
(counterclockwise), and look from all sides to check
that the needle falls at the center of the opening in the
needle plate.
If the needle or feed dogs contact the needle plate, the
machine may be malfunctioning; therefore, contact
your authorized Baby Lock retailer.

Turn off the machine, and then install the bobbin and
presser foot.
Never use a scratched or damaged presser foot.
Otherwise, the needle may break, or sewing
performance may suffer.
