STITCHES ARE

SKIPPING

Troubleshooting

•Replacetheneedleoen,normallyonceortwiceperdayfor

continuous quilting or at least once per quilt. Use only needles

authorized by Baby Lock.

•Alwayschangetheneedleiftheneedlehasstruckanyhardobject

such as a straight pin, etc. e tip of the needle can become damaged

or burred, resulting in fabric damaged as well as skipped stitches and

thread breakage.

•Alwayschangetheneedleifithasbeenhit,bumpedorpulledo

center while maneuvering the machine about the quilt. A slightly

bent needle can be a major cause of skipped stitches.

•Checkforthepropersizeofneedlefortheworkandthreadbeing

applied to the quilting operation. Some battings and fabrics used

in quilting may constrict or impede the thread passing through the

front groove of the needle. is diminishes the loop li 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 specic problems.

•Positiontheneedleproperlytotheneedlebar.Inspecttheposition

of the needle to make sure that the needle is at the 6 o’clock position.

If you stand directly in front of the needle (facing the bobbin case

side of the machine), you will see the entire needle eye directly

facing you. is is 6 o’clock position. For most needle and thread

combinations this is the correct position. However, if you nd your

thread is shredding, you might try positioning the needle to 5 o’clock.

If it is skipping stitches, try rotating the needle eye to 7 o’clock.

•7o’clockisthemaximumtoleranceforrotation.Makesurethe

needle is installed all the way into the needle bar to the needle stop

hole in the needle bar and the long groove is toward the front (bobbin

case side) and the scarf/scooped out part is toward the handwheel.

•Loosenfabricontheframe.Fabricthatisrolledtootightcauses

the bers to separate. is reduces the needle friction on the thread

resulting in a smaller thread loop and may cause skipped stitches.

•Loosenuppertension.

•Inspectthatthethreadtake-uplever,threadstirruportension

spring are all threaded correctly and that the thread is “ossed” into

the tension discs.
