Sewing Machine: Skipping stitches

The sewing machine needle can't hook the bottom thread and skips stitches when you use the wrong needle size for the thread and fabric. A dull or bent needle will also cause skipped stitches as can tight upper thread tension. Adjust the upper thread tension if necessary.

These repairs may help solve your Sewing Machine problem:

Adjust the sewing machine needle timing

Needle

If the machine won’t pick up the bobbin thread because the shuttle hook isn’t synched with the needle, adjust the needle timing.. Adjustment of the needle timing usually requires service by a technician. Using special tools, the technician positions the needle and loosens the shuttle drive gear set screws then adjusts the shuttle drive gear to synchronize the shuttle hook with the needle.

Clean the sewing machine

Shuttle race

Clean lint and debris from the shuttle race every 3 months because it often attracts lint and dust. Clean the feed dogs at the same time because they also attract lint and dust. Clean those areas more often when using the sewing machine regularly. Oil the sewing machine after cleaning.
