Which bobbin should I use?

Needles, bobbins, feet and other details for this model. Check the requirements before choosing parts.
Before choosing a part
Compatibility essentials
Start with these documented details. Read the requirements with each answer before choosing a needle, bobbin or foot.
- Foot attachment
Raise the needle and lock the controls before changing the foot. The ordinary foot releases with the holder’s black button; its pin snaps into the holder notch as the lever is lowered. Use the correct machine-specific foot for the stitch, in the correct direction, and follow the complete procedure. This does not identify a standard shank or confirm another foot fits.
Requirements and sources →- Bobbin type / class
The manual names plastic Class 15 (A style) bobbins.
Requirements and sources →- Bobbin material
Supplied bobbin: plastic, 11.5 mm high. Use only the same type as the supplied Class 15 (A style) bobbin; matching a class label or height alone does not confirm a substitute fits.
Requirements and sources →- Bobbin height
- Needle system / designation
Use home sewing machine needles in the manual's stated size range.
Requirements and sources →- Needle sizes by fabric and use
Not yet confirmed here: Manufacturer accessory group, Presser-foot shank type, Foot holder / mount, Foot interface / generation, Bobbin diameter, Hook type, Maximum stitch / zigzag width, Feed system, Bobbin loading direction. What is still to confirm →
Model & names

Needle, bobbin & presser-foot details
Read the model-specific requirements with each answer before choosing parts.
Needle
System type
- No standardized system code or cross-brand product equivalence is asserted.
Use home sewing machine needles in the manual's stated size range.
Needle insertion
- Cover the needle-plate hole first; an incompletely inserted or loose needle can break or damage the machine.
Raise the needle, lock all keys and buttons, loosen and remove the old needle, then insert the straight replacement fully to the stopper with its flat side facing back and securely tighten the clamp screw before unlocking the controls.
Sources and pages
Fabric thread point conditions
- Keep the two heavyweight rows distinct, follow the table and trial-sew; an improper fabric, thread and needle combination can bend or break the needle.
Use 65/9-75/11 for lightweight fabrics and 75/11-90/14 for medium fabrics. For heavyweight fabrics, the 30-weight polyester/cotton denim-or-canvas row requires 100/16; the separate listed heavyweight row uses polyester 60 or cotton/silk 30-50 with 90/14-100/16. Use ballpoint 75/11-90/14 for stretch fabrics, and never use thread weight 20 or lower.
Sources and pages
Bobbin
Exact compatible item
- The bobbin class and same-type substitution boundary are reported separately; no cross-brand equivalence is established.
The supplied bobbin is plastic and 11.5 mm high.
Sources and pages
Substitutions
- Height, material and class remain inseparable from the source's same-type restriction.
Only a bobbin of the same type as the supplied 11.5 mm plastic Class 15 (A style) bobbin is supported.
Sources and pages
Class system
- This does not establish every marketed Class 15 bobbin as interchangeable.
The manual names plastic Class 15 (A style) bobbins.
Sources and pages
Presser foot
Attachment mount mechanism
- Use the correct foot for the selected stitch and install it in the correct direction before sewing.
Raise the needle, lock the controls, raise the foot lever, press the holder's black button to remove the foot, align the replacement foot pin with the holder notch and lower the lever until the pin snaps into the notch, raise the presser-foot lever to check that the foot is securely attached, then unlock the controls.
Sources and pages
OEM compatibility boundary
- No standardized shank, universal fit, third-party fit or cross-brand compatibility is established.
Use presser feet made for this machine.
Sources and pages
Standardized shank class
Not yet verified- Not yet verified: The reviewed exact manual pages do not name a standardized or low shank class.
Specifications & documented facts
Specifications apply to the named model and document edition. Read any setup, fabric or safety requirements with the answer.

Owner features
Lubrication
- Stop using the machine and contact an authorized retailer for a difficult handwheel or unusual noise; do not oil the bobbin case.
Do not oil the machine as an owner; the manual says its manufacturing oil makes periodic oiling unnecessary.
Cleaning
- The BLAN procedure does not instruct removal of the presser-foot holder. Do not oil the bobbin case or use a scratched case; correctly secure any removed needle plate before reinstalling the case.
Raise the needle, switch the main power off and unplug, remove the needle, foot, flat-bed attachment, needle-plate cover and bobbin case, then brush or vacuum lint and dust from the race, bobbin-thread sensor and surrounding area before reinstalling the case in the illustrated alignment and replacing the cover.
Care, setup & service references
Use the full source procedure and its safety precautions. A short referenced answer is not a substitute for service documentation or qualified electrical/mechanical repair.
Service-manual availability and service-only procedures remain unestablished unless separately cataloged and reviewed.
Coverage and source-review limits
This guide uses model-specific manual instructions for bobbins, needles, presser feet and care. Keep each fabric, thread and needle-size recommendation together. Standard shank classification, broader substitutions and third-party foot fit have not been confirmed.
Coverage and remaining questions
- Operating manual
- Listed below; check the edition and available link.
- Manufacturer part references
- The manual describes the required bobbin type; a bobbin part number is not confirmed here. Other replacement parts and aftermarket fit have not been confirmed.
Still to confirm
