5. Operating Instructions
5.1 Threading the Machine
Proper threading is crucial for consistent stitch quality. Follow the threading path carefully, ensuring the thread passes through all guides, tension discs, and the take-up lever before entering the needle eye.
Figure 1: Roller foot and threading path. The yellow thread is guided through the machine's components towards the needle.
Figure 2: Post-bed design with needle and presser foot area. The elevated post bed facilitates sewing on three-dimensional items.
5.2 Adjusting Stitch Length
The stitch length can be adjusted using the dial located on the side of the machine head. Rotate the dial to select a stitch length between 1 mm and 5 mm. For longer stitches, the machine supports up to 8 mm (approximately 6-16 stitches per inch).

5.3 Reverse Stitching
To reinforce stitches, especially at the beginning and end of a seam, use the spring-loaded reverse lever. Press and hold the lever to sew in reverse; release it to resume forward stitching.
5.4 Presser Foot Operation
- Roller Foot: The machine comes equipped with a heavy-duty roller foot and roller feed, ideal for controlling thick materials like leather.
- Changing Presser Foot: The roller presser foot can be changed to a flat presser foot if desired, depending on the material and application.
- Knee Lifter: Use the knee lifter mechanism to raise the presser foot. This allows for hands-free lifting, providing a lift of approximately 1/2" (10 mm). The presser foot can also be lifted by hand up to 1/4" (7 mm).
5.5 Sewing Speed
The iKonix KS-810 is capable of sewing at speeds up to 2,500 to 3,000 stitches per minute (s.p.m.) with steady precision. Adjust your motor speed control for optimal performance based on material thickness and stitch complexity.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your sewing machine.
- Oiling: Regularly oil all moving parts and designated oiling points with high-quality sewing machine oil. Refer to the machine's specific oiling diagram for precise locations. The included oil pan helps manage lubrication.
- Cleaning: Keep the machine clean from lint, dust, and thread scraps. Use a brush or compressed air to clean the bobbin area, feed dogs, and tension discs.
- Needle Replacement: Replace needles frequently, especially when sewing thick or tough materials, or if the needle shows signs of bending or dullness. Use only DPx5 #14 (Standard) needles or equivalent.
- Belt Tension: Periodically check the motor belt tension. It should be taut enough to prevent slipping but not so tight as to strain the motor or machine bearings.
7. Troubleshooting
This section addresses common issues you might encounter. For more complex problems, consult a qualified sewing machine technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Skipped Stitches | Incorrect needle, bent needle, improper threading, incorrect tension. | Replace needle (DPx5 #14), re-thread machine, adjust tension. |
| Thread Breakage | High tension, burr on needle/thread path, poor quality thread, incorrect needle size. | Reduce tension, check thread path for rough spots, use quality thread, ensure correct needle. |
| Uneven Stitches | Incorrect tension, worn feed dogs, inconsistent material feeding. | Adjust tension, clean feed dogs, ensure consistent material handling. |
| Machine Jams | Thread tangled in bobbin case, lint buildup, incorrect bobbin winding. | Clear bobbin area, clean machine, re-wind bobbin correctly. |
