- Stitch Length: Adjustable from 0.5 mm to 5.3 mm. Use the stitch length dial, typically located on the side of the machine head, to set the desired length.
- Overedge Width: The standard overedge width is 4 mm. Adjustments can be made by modifying the knife position or needle plate, as detailed in the machine's specific technical manual.
4.3 Basic Operation
Once threaded and adjusted, turn on the main power switch. Use the foot pedal to control the sewing speed. Guide the fabric evenly under the presser foot. The machine is suitable for a wide range of fabrics, including light, medium, and heavy materials, making it versatile for various garment constructions such as lingerie, swimwear, sweatshirts, shirts, pants, t-shirts, and shorts.

- Thread Breakage: Check for correct threading, proper tension settings, burrs on thread guides, or a damaged needle.
- Poor Stitch Quality: Adjust thread tension, check for correct threading, and ensure the needle is sharp and appropriate for the fabric.
- Excessive Noise/Vibration: Check for loose parts, ensure proper lubrication, and verify that the machine is correctly assembled on its stand.
For persistent issues, consult a qualified sewing machine technician.
