Before choosing a part
Start with these documented details. Read the requirements with each answer before choosing a needle, bobbin or foot.
Organ or Schmetz ELx705CF needles: size 90/14 for most medium and heavyweight fabrics, size 80/12 for lightweight fabrics. The ELx705CF is a semi-ballpoint design, suitable for both knits and wovens.
Requirements and sources →Not yet confirmed here: Manufacturer accessory group, Presser-foot shank type, Foot attachment, Foot holder / mount, Foot interface / generation, Bobbin type / class, Bobbin material, Bobbin diameter, Bobbin height, Hook type, Maximum stitch / zigzag width, Feed system, Bobbin loading direction. What is still to confirm →
Other names, regional versions and related models have not been confirmed here. A shared manual, product line or accessory group does not identify the machine's family.
Organ or Schmetz ELx705CF in 80/12 to 90/14, as the guide’s technical data lists. The guide states no other needle system or size, so others are not confirmed here.
Documents and page references →Switch the machine to “O” (off) before changing the foot, and use the “To Release” and “To Replace” steps on PDF page 15 (printed page 12). The guide gives no shank class and does not say which third-party feet fit.
Documents and page references →Widths are given per stitch type, as printed in the technical data; there is no single maximum. The 16.0 mm figure applies only to the named combined stitches, and width-dial settings are not given here.
Documents and page references →Values are the guide’s ranges. Test the differential setting on your fabric, because fabric weight affects how it gathers.
Documents and page references →Unplug the machine after use and before cleaning, and unplug the main power cord before removing the needle plate (PDF page 78, printed page 75).
Documents and page references →The guide never mentions a bobbin or bobbin case. That is treated as not stated, not as ruled out.
Documents and page references →Switch the machine to “O” (off) first. Use the guide’s four steps under “To replace a needle” on PDF page 76 (printed page 73), then check the needle viewing window, tighten the needle clamp screw and close all covers before sewing.
Documents and page references →The pressure is preset and rarely needs changing. The guide suggests less pressure for thick fabrics and more for thin ones, so that they feed smoothly.

Read the model-specific requirements with each answer before choosing parts.
Organ or Schmetz ELx705CF needles: size 90/14 for most medium and heavyweight fabrics, size 80/12 for lightweight fabrics. The ELx705CF is a semi-ballpoint design, suitable for both knits and wovens.
Switch the machine off (symbol "O") first. Then follow the manual's four steps under "To replace a needle" on PDF 76 / printed 73. Before sewing, check that the needle is inserted as far as it will go (look in the needle viewing window), that the needle clamp screw is tightened, and that all machine covers are closed. Needle positions: the chain/cover stitch needles C-1, C-2 and C-3 are at the front left of the needle clamp; the overlock needles O-1 and O-2 are at the back right.
Switch the machine off (symbol "O") before changing the foot. Then follow the manual's "To Release" and "To Replace" steps on PDF 15 / printed 12; both start with the needles raised to their highest position, the presser foot lever raised and the cutting blade locked down. The machine uses a snap-on presser foot system; the technical data lists "Snap on exclusive feet for Splendor".
The presser foot pressure is preset and rarely needs adjustment. To change it, turn the presser foot pressure adjustment dial on the left side of the machine: counterclockwise to increase the pressure, clockwise to decrease it.
Specifications apply to the named model and document edition. Read any setup, fabric or safety requirements with the answer.
It depends on the stitch; there is no single maximum width. Overlock: 5.5-7.5 mm with the left needle (standard 2/3/4-thread), 3.0-5.0 mm with the right needle (standard 2/3-thread), and 1.5 mm for the 3-thread rolled hem with the right needle. Cover stitch: 6.0 mm for wide or triple, 3.0 mm for narrow. Combined stitches (5-thread safety stitch and 6-, 7- and 8-thread ultra stitches): up to 16.0 mm.
No routine oiling: the manual says the major moving parts are well protected and do not need to be oiled. Use the cleaning brush often to keep lint off the blades, the needle bar, the feed dog mechanism and the loopers, and schedule regular routine maintenance with an authorized Baby Lock retailer.
Stitch length ranges from 0.75 to 4.0 mm. Differential feed: settings from N (normal feeding) to 2 gather the fabric, and settings from N to 0.6 stretch it. At the maximum setting of 2.0 it can gather a lightweight fabric.
Three loopers: upper (U), lower (L) and chain (C). The guide names no bobbin or bobbin case.
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.
Answers use this model’s own instruction manual with its stated safety conditions. Where the manual contradicts itself or gives no value, no answer is given. No hands-on testing or replacement-part fit is claimed.
An unanswered question does not mean a part is incompatible. We have not confirmed enough information to recommend it.
Other names, regional versions, production history, further specifications and documents are not fully covered here. Their absence is not a “none exist” finding.
