Baby Lock Soprano

Home sewing machine needle system HA × 130.

• Use the size and needle type assigned to the fabric and thread; ball-point 75/11–90/14 is specified for stretch fabrics.

The OEM table covers sizes 65/9 through 100/16, with fabric, thread and point-specific choices.

• Tighten the needle-clamp screw securely with the screwdriver.

Insert the needle with its flat side toward the rear until it touches the stopper.

• Do not use the threader with a wing needle or twin needle; specialty and transparent monofilament threads are not recommended with it.

The needle threader supports machine-needle sizes 75/11 through 100/16.

Class 15 type.

• The manual says to use the included bobbin or the same X52800-120 type and warns against bobbins from other models.

Baby Lock X52800-120.

• The reviewed passage establishes height and OEM type; material and broader substitution equivalence remain unknown.

Approximately 11.5 mm (7/16 inch) high.

• Hold the bobbin down and guide the thread through the needle-plate-cover slit as shown by the OEM instructions.

Insert the bobbin in its case with the thread unwinding to the left.

• Align the foot pin with the holder notch and lower the holder until it snaps on. This establishes the foot-to-holder connection only.

Ordinary presser feet snap onto the presser-foot holder.

• Use a screwdriver to remove or attach the holder. This establishes the OEM holder arrangement, not a standardized shank class.

The presser-foot holder is removable and secured to the presser bar by its holder screw.

• The passage names these foot types but does not establish every compatible walking or quilting foot.

Remove the holder when installing a walking foot or quilting foot that does not use it.

• Only exact accepted Soprano BLMSP and this retained Baby Lock August2025 accessory catalog; other names, suffixes, generations and regions remain separate.
• This is a manufacturer chart classification, not dimensions, a universal adapter/holder promise, an offered retail unit, supplied equipment or proof that every accessory in the group fits. Follow exact manual and accessory conditions.
• Keep the printed G/L code: G is the accessory group; L uses the existing evidence engine low-shank mapping. No measured shank height, interchangeable holder or generic foot fit is established.

Low shank (the OEM group/shank chart prints G/L).
