| Specification |
Details |
| Model / Subclass |
Dürkopp Adler 869-180322-M / E2 |
| Machine Type |
Single-needle industrial cylinder arm sewing machine |
| Stitch Type |
301 lockstitch |
| Feeding System |
Bottom feed, needle feed and alternating presser feet (triple feed) |
| Hook |
Large vertical hook |
| Cylinder Arm Diameter |
78 mm |
| Working Clearance |
335 mm wide × 125 mm high |
| Maximum Stitch Length |
Up to 9 mm with E2/9 equipment. Confirm the supplied E2 version; some alternative equipment configurations are limited to 6 mm. |
| Maximum Sewing Speed |
Up to 2,800 stitches per minute. Reduce speed for high foot stroke, difficult materials, curves and seam intersections. |
| Alternating-Foot Stroke |
Adjustable up to 9 mm. |
| Maximum Lifted-Foot Clearance |
Up to 20 mm. This is foot-lift clearance, not a guaranteed sewing-thickness capacity. |
| Maximum Material Thickness |
No universal sewable thickness in millimetres has been verified. The manufacturer lists 10 mm clearance when sewing and up to 20 mm when lifting the feet. Neither figure guarantees the machine can sew material of that thickness. Density, compressibility, needle, thread and seam structure determine the workable limit. Request a sample-sewing test. |
| Maximum Thread Size |
Machine-class capability is listed up to Nm 10/3. This is a thread count, not a diameter in millimetres, and does not guarantee compatibility with the supplied E2 tooling. Confirm needle-eye clearance, thread, hook and trimmer setup. |
| Needle System |
134-35 |
| Needle Size |
E2/9 equipment is listed for Nm 110–140 needles, with Nm 140 as its upper listed size. The broader machine-class range is Nm 90–180 depending on equipment. Do not assume Nm 180 is suitable for E2. Select the needle point to suit the material. |
| Drive and Controls |
Integrated DA direct drive, DAC classic control and OP1000 panel in the documented standard model configuration. Confirm the delivered configuration. |
| Automatic Functions |
Documented CLASSIC configuration includes thread trimming, automatic backtacking and pneumatic presser-foot lift. Confirm the supplied package. |
| Air Supply |
Manufacturer-listed operating pressure: 6 bar. Air consumption: 0.7 NL per working cycle for pneumatic functions. Confirm compressor and air-treatment requirements. |
| Reference Setup Dimensions |
1,200 × 550 × 1,700 mm (L × W × H), manufacturer-listed reference dimensions for 869-180322-M. Actual supplied table, stand, thread stand and installed height must be confirmed in the quotation. These are not measurements of Ban Soon's assembled unit. |
| Machine-Head Height / Table Working Height |
Exact installed head height and table working-height range are not verified for this package. The 1,700 mm figure above is the overall reference setup height, not the table height. |
| Selling Price |
S$16,845 |
| Warranty |
12 months. Coverage and exclusions are subject to the supplied warranty terms. |
Presser Feet and Optional Sewing Equipment
This machine uses a matched alternating presser-foot and feeding-foot arrangement rather than domestic snap-on presser feet. The needle plate, feed dog, presser feet and needle clearance must be compatible with one another.
| Equipment Option |
Purpose and Technical Details |
| E2/9 Edge-Stitching Equipment |
Documented for medium-weight material, Nm 110–140 needles, up to 9 mm stitch length and an 8 mm feed-dog width. Confirm that the E2 designation in your quotation refers to this version. |
| Welt / Piping Equipment |
The 869 equipment catalogue lists E7/6 for a 5 mm attaching groove, Nm 110–140 needles and up to 6 mm stitch length. Order a matched set after checking the exact subclass and intended seam sample. |
| Narrow Edge-Stitching Equipment |
The catalogue lists E11/9 for stitching 1 mm to the right of the needle, Nm 110–140 needles and up to 9 mm stitch length. Confirm current part numbers and subclass fit before ordering. |
| Binding Equipment |
Model-specific binding equipment appears in supplier listings, including E05006. Binder geometry, material and complete tooling compatibility require confirmation. A presser-foot-only replacement is not assumed to be sufficient. |
Troubleshooting and Repair Guidance
The following are practical troubleshooting scenarios, not a verified ranking of this model's failure frequency.
Switch off and isolate electrical power before touching the needle, hook, presser feet or thread trimmer. Isolate and release compressed air before pneumatic work. Timing, electrical and pneumatic repairs should be handled by a trained technician.
| Symptom |
Checks and Repair / Replacement Guidance |
| Skipped Stitches or Needle Breakage |
Stop immediately and safely remove any broken needle fragments. Replace a bent, blunt or damaged needle with the correct 134-35 size and point within the fitted equipment's range. Install it in the orientation and depth specified in the manual, rethread and test slowly on scrap material. If needle contact or skipped stitches persist, stop and have a technician inspect hook timing, clearances and tooling alignment. |
| Thread Breakage, Loops or Irregular Tension |
With power isolated, check the threading path, bobbin winding and thread-to-needle match. Clean lint from accessible areas and inspect for damaged needles or burrs. Replace the needle or damaged bobbin as appropriate, rethread and restore balanced tension on scrap material. Have a technician repair or replace a burred hook or plate; avoid filing precision components without proper guidance. |
| Thread Trimmer Does Not Cut Cleanly |
Isolate power and air before accessing the trimmer area. Remove loose thread and lint without forcing the mechanism. Check threading and thread suitability, then restore guards before testing. Persistent failure requires a technician to inspect knife condition, timing and actuation, replace the correct worn knife components and verify cutting performance and needle clearance. |
Operator Maintenance Guide
Switch off and isolate power before cleaning, threading near moving parts or changing needles. Isolate and release compressed air before pneumatic maintenance. At each shift, inspect the needle, thread path, bobbin and guards. Replace bent or blunt needles with the correct system, size and point. Remove lint and loose thread from accessible needle, hook, bobbin and trimmer areas with a soft brush; clean more often when using lint-producing materials. Keep motor ventilation openings clear. Check oil level against the reservoir marks and refill only as directed in the operating manual, using DA 10 or the specified equivalent. Do not overfill or adjust hook lubrication without training. Inspect the air supply and water separator according to the manual. After cleaning, refit guards and test on scrap at low speed. Record unusual noise, leaks, skipped stitches or poor trimming, and stop if contact or jamming occurs. Have a qualified technician handle timing, knife adjustment, electrical work and scheduled servicing.

The equipment catalogue lists certain sewing equipment against subclasses 869-180020, 869-180122 and 869-180322. This is equipment-specific documentation; it does not confirm that all parts, controls, presser feet or attachments are interchangeable with this -M machine.
No exhaustive cross-model compatibility list has been verified. Do not assume compatibility with twin-needle 869-280xxx machines, 669, 867, 868, 969, PREMIUM or e-con variants.
For spare-part and accessory enquiries, provide:
- Full machine subclass and model designation
- Machine serial number
- Installed sewing-equipment number
- Original part number, if available
- A photograph of the existing component, where possible
This information helps verify the correct replacement before ordering.
