problem:
Adjust the sewing machine needle timing
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.
