Needle styles and sizes · fabric and task limits
Read limits before choosing a needle
- General needle overview in the exact retained B330/B350 Patchwork Edition/B380 shared manual only; source material/use remains attached to each row.; Preserve grouped/abbreviated OEM codes exactly; no expansion into identity synonyms, universal replacements or unrestricted formal-system equivalence.; Twin/triple/wing entries are chart guidance, not proof of safe clearance for every stitch/foot/plate or a maximum machine stitch width. Needle-distance units are not printed in this chart and are not inferred.; The separate accepted needle-changing procedure requires raising the needle, switching power off and lowering the presser foot before removal. Preserve that original physical18 procedure and conditions.; No B325/B335 or other sibling-model fanout; no retail fitment, product navigation or actual installed-needle guarantee.

Bobbin
Bobbin insertion
- Follow the OEM slot and spring routing shown in the manual.
Insert the bobbin with its thread running clockwise; after routing the thread through the slot and under the spring, the bobbin must still turn clockwise.
Class system
Not yet verified- Not yet verified: The reviewed passages do not state a standardized bobbin class.
Substitutions
Not yet verified- Not yet verified: No cross-brand or generic bobbin substitution is established.
Presser foot
Sole attachment
- Place the sole so its peg is under the shaft opening, then lower the presser-foot lifter. This proves the OEM sole-to-shaft attachment only, not universal third-party foot fit.
The presser-foot sole clicks onto the machine's presser-foot shaft.
Standardized 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
Routine cleaning
- Switch off and unplug first; never use a sharp instrument in the hook race.
After every use, remove lint from under the stitch plate and in the hook area; clean the hook race with a cloth or brush.
Hook race lubrication
- Switch off and unplug before lubricating; the thread-free run helps prevent oil from soiling the work.
Apply one or two drops of oil to the hook race, then briefly run the machine without thread.
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
The original source author’s manual research is reused here; it is not a new manufacturer certification. Standard bobbin class, substitutions, shank and third-party compatibility remain unconfirmed.
Coverage and remaining questions
- Operating manual
- Listed below; check the edition and available link.
- Exact OEM part application
- No model-specific part application is listed here.
Still to confirm
An unanswered question does not mean a part is incompatible. We have not confirmed enough information to recommend it.
Presser foot — Standardized shank class: Not established Full recorded limit & conditions →
Presser foot — Third party fit: Not established Full recorded limit & conditions →
Bobbin — Class system: Not established Full recorded limit & conditions →
Bobbin — Substitutions: Not established Full recorded limit & conditions →
Other names, regional versions, production history, further specifications and documents are not fully covered here. Their absence is not a “none exist” finding.
Next evidence targets
- Establish replacement-foot, shank and mount applicability separately from the documented sole-attachment procedure.
- Establish the exact bobbin class, OEM part identifiers and dimensions without inferring them from insertion instructions.
- Add exact stitch-width and hook-system evidence while preserving the current recorded limits.
These are research questions, not claims that the missing relationship exists.
