Troubleshooting
Skipped Stitches
Corrective Measure
•
The needle is damaged, dull, bent,
or installed improperly
•
Replace the needle often, normally once or twice per day for
continuous quilting or at least once per quilt. Use Baby Lock Tiara III
recommended needles.
•
Always change the needle if the needle has struck any hard object
such as a straight pin, etc. The tip of the needle can become damaged
or burred, resulting in fabric damage as well as skipped stitches,
thread breakage or shredding. Damaged needles cannot always be
identified with the naked eye.
•
Always change the needle if it has been hit, bumped or pulled off
center while maneuvering the machine around the quilt. A slightly
bent needle or needle burr can be a major cause of skipped stitches.
•
Incorrect needle size
•
Very tightly-woven fabric (such as
batiks)
•
Check for the proper combination of needle size and thread weight
being applied to the quilting operation. Some fabrics used in quilting
may constrict or impede the thread passing through the front
groove of the needle. This diminishes the loop lift required for stitch
formation. Typically, a larger needle will solve the problem; however,
it has been found that certain smaller sizes of needles as well as the
use of ball-pointed needles solve some specific problems.
•
Needle has not been positioned
properly
•
Position the needle properly to the needle bar. Inspect the position
of the needle to make sure the needle is at the 6 o’clock position (see
Inserting (or Changing) the Needle
, Figure 8). When you’re sitting
directly in front of the needle (facing the bobbin case side of the
machine), you will see the entire needle eye directly facing you. This is
6 o’clock position.
•
Make sure (1) the needle is installed all the way inside the needle
bar to the needle stop hole in the needle bar, (2) the long groove in
the needle is toward the front (bobbin case side), and (3) the scarf/
recessed part of the needle is toward the handwheel. The needle can
sometimes be rotated to 5 o’clock (slightly right) or 7 o’clock (slightly
left) in order to adjust for a more positive thread loop pickup by the
hook point.
•
Thread tension too tight
•
Loosen top tension. Re-check top and bobbin tension. (See B
obbin
Case and Bobbin Thread Tension Adjustments
and
Top Thread Tension
Adjustment.
).
•
Improper threading
•
Inspect that the thread take-up lever, thread stirrup or tension spring
are all threaded correctly.
