What do you need help with?
How do I insert and thread the bobbin?
Before you use this answer
Follow the exact illustrated insertion and threading procedure. These steps do not establish a replacement bobbin class or substitution.
Documents and page references →Which needles does this manual recommend for different fabrics?
Before you use this answer
Keep the stated needle, size, fabric and thread conditions together; recommendations do not establish every special-use or third-party needle.
Documents and page references →How do I clean the machine?
Before you use this answer
Read the complete cleaning procedure and its power-off or disconnection requirements before starting.
Documents and page references →How do I insert a replacement needle?
Before you use this answer
Follow the illustrated insertion procedure and all power-off conditions. Insertion direction does not establish a different needle system.
Documents and page references →What does the manual say about lubricating the hook race?
Before you use this answer
Follow the exact hook-race instructions, oil requirements and safety conditions in this edition. Do not extend them to other machine areas.
Documents and page references →More questions (2)
What maximum stitch width does this exact catalog state?
Before you use this answer
The retained catalog gives 5.5 mm for this exact LCD-era model. Read its edition/country limits; each foot, plate and twin needle has its own limits.
Documents and page references →Which hook system does this exact catalog name?
Before you use this answer
The model row says CB, expanded by this catalog to CB Hook (central bobbin). This does not establish a numbered bobbin class, dimensions, material or interchangeable replacement.

Needle, bobbin & presser-foot details
Read the model-specific requirements with each answer before choosing parts.
Needle
System and sizes
- Universal is listed as 130/705 H in sizes 60-100; other rows specify their own system suffixes and size ranges.
The OEM overview centers on the 130/705 H household-needle family, with system variants and sizes selected by material and use.
Sources and pages
Material specific selection
- Keep the manual's stated size ranges: 70-90 for jersey/stretch and 90-100 for leather.
Use the listed needle variant for the material: ball-point variants for jersey/stretch and LL or LR cutting-point variants for leather and plastic film.
Sources and pages
Needle insertion
- Raise the needle, switch power off and lower the presser foot before removal.
Insert the needle fully with the flat side facing the back, then tighten the clamp screw.
Sources and pages
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.
Sources and pages
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.
Hook system
- The 50-page English BERNINA machine catalog; the named B 325 and B 335 models in this LCD-era document only.
- Catalog says models/accessories are not available in all countries and features/equipment/design may change; no current generation or regional equipment transfer.
- The literal CB code is expanded only by this printed legend, not by generic hook terminology.
- No numerical bobbin class, part substitution, bobbin material/dimensions, replacement hook or retail fitment is established.
CB Hook (central bobbin)
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.
Sources and pages
Standardized shank class
Not yet verified- Not yet verified: The reviewed passages do not state a standardized low-, high- or other shank class.
Third party fit
Not yet verified- Not yet verified: No third-party presser-foot or adapter compatibility is established.
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.
Sources and pages
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.
Sources and pages
Performance & stitch capabilities
Maximum stitch bight mm
- The 50-page English BERNINA machine catalog; the named B 325 and B 335 models in this LCD-era document only.
- Catalog says models/accessories are not available in all countries and features/equipment/design may change; no current generation or regional equipment transfer.
- Native text order alone is not model ownership: visible continuation row across physical48/49 and printed model on49 plus exact width heading/cell on48 are both required.
- The table states a machine maximum; it does not authorize every presser foot, plate, twin needle or accessory at this width.

Identity
Manufacturer series
- Manufacturer-series wording for the exact accepted B 335 entity in this record’s cited catalog. Keep the catalog edition and exact-model scope attached.

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.
