Model & names

- Baby Lock BLE1AT-2
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.
What do you need help with?
Which presser feet fit the BLE1AT-2?
Before you use this answer
Codes are as printed. The manual says nothing about other brands’ feet, so their fit is unknown, not incompatible. It says the optional feet are available from a Baby Lock retailer; no retailer fit is claimed here.
Documents and page references →Where are the tension dials?
Before you use this answer
The manual says most fabrics and threads need no adjustment; the looper fine-tuning screw is only for certain threads or fabrics.
Documents and page references →The air threading won’t push the thread through a looper. What should I check?
Before you use this answer
Looper threading needs the machine in the locked position. The thread-tail length is given in inches only, because the manual prints two different metric figures for it.
Documents and page references →Do I need to oil it?
Before you use this answer
The manual says no and names no oil type; if oil ever seems needed, it refers owners to a Baby Lock retailer.
Documents and page references →How do I change a needle, and what if one drops into the machine?
Before you use this answer
Switch the power off (“O”) first. Use “Replacing Needles” on PDF page 48 (printed page 46) and its needle viewing window check.
Documents and page references →More questions (3)
How do I take the presser foot off and put it back?
Before you use this answer
Switch the machine to “O” (off) first. Use “Snap-On Presser Foot”, To Release and To Replace, on PDF page 20 (printed page 18).
Documents and page references →What thread works best?
Before you use this answer
The named brands are the manual’s recommendations, not a compatibility list. Specialty threads are covered on PDF pages 46–47 (printed pages 44–45).
Documents and page references →Can I replace the cutting blades myself?
Before you use this answer
Unplug the main power cord first, as step 1 says. Use “TO REPLACE MOVING BLADE” on PDF page 48 (printed page 46). For the fixed blade, the manual says to contact a Baby Lock retailer.

Needle, bobbin & presser-foot details
Read the model-specific requirements with each answer before choosing parts.
Needle
System and sizes
- The manual prints the system as "HA x 1SP/CR" in the technical data and "HAx1SP/CR" in the needle and troubleshooting text; both are kept as printed. No other needle system is stated.
Organ or Schmetz HA x 1SP/CR. The machine comes set up with 75/11, which suits most medium and lightweight fabrics; the manual says to change to 90/14 for heavyweight fabrics, and to replace needles about every third project. "Are the needles being used the correct Schmetz or Organ HAx1SP/CR system?" is also one of the manual's checks for thread breaks.
Replacement procedure
- Safety instruction 14 (PDF 2, unnumbered) and Dos and Don'ts item 2 (PDF 51 / printed 49) both require the power to be off before changing a needle.
First switch the power off: safety instruction 14 says to switch the machine to "O" when changing a needle (PDF 2), and Dos and Don'ts item 2 says to turn the power switch off (PDF 51 / printed 49). Then follow "Replacing Needles" on PDF 48 / printed 46. The manual's completion check is to look in the needle viewing window. A dropped needle lands in the needle-drop drawer at the bottom of the serger (same page).
Presser foot
Compatible feet
- The manual makes no statement about other brands' feet, so that stays unknown, not incompatible.
- Codes are as printed; the manual says the optional accessories are available at a Baby Lock retailer, and no retailer fit is claimed.
Snap-on E-line feet (PDF 52 / printed 50). Baby Lock lists eight optional snap-on feet for this machine by code: Beading Foot B5002-01A-C-E (BLE-BF); Blindhem Foot B5002S02A-E (BLE-BLHFS); Clear Foot B5002K01A-E (BLE-CLF); Cording / Piping Foot (3mm) B5002-02A-C-E (BLE-CF3); Cording / Piping Foot (5mm) B5002-03A-C-E (BLE-CF5); Elastic Applicator Foot B5002S01A-E (BLE-EF); Lace Applicator Foot B5002S05A-E (BLE-LF); Ruffling Foot B5002S03A-E (BLE-RF) (PDF 9 / printed 7).
Attachment
- Safety instruction 14 (PDF 2, unnumbered) says to switch the machine to the "O" position when changing the presser foot.
Switch the machine to "O" first (safety instruction 14, PDF 2). Then follow "Snap-On Presser Foot", To Release and To Replace, on PDF 20 / printed 18. The included foot has a tape-sewing slot, and its raised toe marks are seam-line guides for the needle positions (same page).
Specifications & documented facts
Specifications apply to the named model and document edition. Read any setup, fabric or safety requirements with the answer.
Care
Oiling
- The manual names no oil type; it refers owners to a Baby Lock retailer for high grade recommended sewing machine oil.
No. The manual says the major moving parts are well protected and do not need oil. Brush lint off often from the blades, needle bar, feed dog mechanism and loopers, and if the machine seems to need oil, check with a Baby Lock retailer (PDF 49 / printed 47).
Blade replacement
- Step 1 of the manual's procedure is to unplug the main power cord for safety reasons.
The upper moving blade, yes: a spare comes in the spool-stand accessory compartment. Unplug the main power cord first, then follow "TO REPLACE MOVING BLADE" on PDF 48 / printed 46, whose check is that the top section of the moving blade is set below the fixed blade when the moving blade is at its lowest position. The fixed blade is long-lasting steel, and the manual says to contact a Baby Lock retailer to replace it (same page).
Thread
Tension system
- The manual says no adjustments are needed for most fabrics and threads; the fine-tuning screw is for certain threads or fabrics only.
The manual describes no tension dials: its Thread Delivery System replaces manual tension adjustment (PDF 17 / printed 15). You choose a stitch-selector letter: A for wide overlock stitches; B for the right-needle wave stitch and right-needle overlock stitches; C for narrow stitches and the rolled wave stitch using the right needle; D for the 3-thread rolled hem. If a thread or fabric needs it, the looper thread fine-tuning screw tightens or loosens both looper threads equally; the manual's illustration shows the screw's standard position giving the ideal stitch (PDF 15 / printed 13).
Recommended thread
- The named brands are the manual's recommendations, not a compatibility list.
The manual recommends 100% long-staple polyester, cross-wound on a cone; for best performance it names "100% polyester-long fiber thread", with Maxi-Lock and Metrosene as recommended brands. Cotton works but makes more lint, and it may be too weak or fuzzy for rolled edges (PDF 9 / printed 7). Specialty threads are covered by the chart on PDF 46-47 / printed 44-45.
Threading
Air threading checks
- The thread-tail length is given in inches only; the manual prints two different metric figures for it.
The manual's checklist: is the looper threader selector set correctly ("U" upper, "L" lower)? Is the thread end in the right port, with at least 1 inch (2.5 cm) inserted? Are there at least 18 inches of loose thread beyond the guide, with no kink? Is the thread caught? (PDF 51 / printed 49.) It also says to remove the old thread completely from the looper tube before re-threading (PDF 17 / printed 15). The machine must be in the locked position for looper threading (PDF 12 / printed 10).
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
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.
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.
Other names, regional versions, production history, further specifications and documents are not fully covered here. Their absence is not a “none exist” finding.
