5. Setup
5.1 Machine Placement
The sewing machine head requires a dedicated industrial sewing machine table for proper installation and operation. Ensure the table is sturdy, level, and provides adequate space for material handling.
5.2 Power Connection
- Verify that the power supply matches the machine's voltage requirements (typically 220V, consult local electrical standards).
- Plug the machine's power cord into a grounded electrical outlet.
- Ensure the power switch is in the 'OFF' position before connecting to power.
5.3 Threading the Machine
Proper threading is crucial for consistent stitch quality. Refer to Figure 3 for visual guidance on the upper threading path.
- Place the thread spool on the spool pin.
- Guide the thread through all designated thread guides.
- Pass the thread through the tension discs and take-up lever.
- Thread the needle from front to back.
- Install a properly wound bobbin into the bobbin case and insert it into the machine's bobbin area.
- Pull the bobbin thread up through the needle plate hole using the upper thread.
5.4 Needle Installation
- Turn off the machine and unplug it from the power source.
- Loosen the needle clamp screw.
- Remove the old needle (if applicable).
- Insert the new needle with the flat side facing the correct direction (usually away from the operator or as indicated by the machine).
- Push the needle up as far as it will go.
- Tighten the needle clamp screw securely.
6. Operating Instructions
6.1 Basic Sewing
- Turn on the machine's power switch.
- Place the material under the presser foot.
- Lower the presser foot using the automatic lifting foot function or manual lever.
- Gently press the foot pedal to start sewing. The computerized operation allows for precise speed control.
- Guide the material smoothly through the machine.
- To stop, release the foot pedal.
6.2 Adjusting Stitch Length
The stitch length can be adjusted using the control panel or a dedicated dial, typically ranging from 0-9mm. Experiment with different settings on scrap material to find the optimal length for your project.
6.3 Automatic Thread Cutting
After completing a seam, the machine can automatically cut the upper and bobbin threads. This feature is usually activated via a button on the control panel or a specific foot pedal action. Consult the control panel's specific instructions for activation.
6.4 Automatic Presser Foot Lift
The automatic presser foot lift feature allows the presser foot to raise and lower automatically at the beginning and end of a seam, or when stopping, improving workflow and reducing manual effort.
6.5 Automatic Reinforcement
This feature automatically stitches a few reverse stitches at the beginning and end of a seam to secure the stitching and prevent unraveling. This is typically programmable via the control panel.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your sewing machine.
7.1 Cleaning
- Turn off and unplug the machine.
- Remove the needle plate and bobbin case.
- Use a small brush to remove lint and dust from the feed dogs, bobbin area, and tension discs.
- Wipe the machine's exterior with a soft, dry cloth.
7.2 Lubrication
This machine features automatic lubrication. Ensure the oil reservoir is filled to the appropriate level with recommended sewing machine oil. Check the oil level regularly and refill as needed.
7.3 Needle Replacement
Replace needles frequently, especially when sewing tough materials like leather, or if they become bent or dull. A fresh needle prevents skipped stitches and fabric damage. Refer to section 5.4 for installation steps.
8. Troubleshooting
This section addresses common issues you might encounter during operation.
| Problem | Possible Cause | Solution |
|---|---|---|
| Skipped Stitches | Incorrect needle, bent needle, improper threading, incorrect tension. | Replace needle with correct type/size, re-thread machine, adjust tension. |
| Thread Breakage | Poor quality thread, incorrect tension, burr on needle plate, damaged needle. | Use quality thread, adjust tension, check for burrs, replace needle. |
| Uneven Stitches | Incorrect tension, inconsistent material feeding. | Adjust tension, ensure smooth material feeding. |
| Machine Not Starting | Not plugged in, power switch off, safety features engaged. | Check power connection, turn on switch, disengage safety features. |

10. User Tips
- Use the Right Needle: For leather, always use a leather-specific needle (e.g., a wedge point or chisel point needle) to cleanly pierce the material without tearing.
- Choose Appropriate Thread: Use strong, durable thread suitable for leather, such as bonded nylon or polyester.
- Test on Scraps: Before sewing your main project, always test stitch length and tension on a scrap piece of the same material to ensure optimal results.
- Regular Cleaning: Leather sewing can generate more lint and dust. Clean the bobbin area and feed dogs frequently to prevent buildup and maintain smooth operation.
- Proper Material Handling: Guide the leather gently; do not pull or push forcefully, as this can bend needles or distort stitches.
