5.2. Bobbin Winding

The machine features an integrated bobbin winder. Place an empty bobbin onto the winder spindle, guide the thread as instructed, and engage the winder. The large M-style industrial bobbin allows for extended sewing without frequent changes.

5.3. Adjusting Stitch Length

The maximum stitch length is 5 mm. Adjust the stitch length dial on the machine head to achieve the desired stitch size for your material.

5.4. Presser Foot Lift

The presser foot can be lifted by hand (max. 5.5 mm) or by using the knee lifter (max. 13 mm). This high lift capacity is beneficial for handling thicker materials.

5.5. Servo Motor Speed Control

The Electronic DC Servo Motor offers variable speed control from 0 to 3300 RPM, allowing for precise speed adjustments suitable for various sewing tasks and materials.

• Cleaning: Keep the machine head and surrounding area clean from lint and dust. Use a soft brush or cloth.
• Needle Replacement: Replace needles regularly, especially when working with different materials or if the needle shows signs of wear. Recommended needles: 9-18 DBX1 (16x231) up to size 19.

7. Troubleshooting

If you encounter issues, refer to the following common troubleshooting tips:

• Skipped Stitches: Check if the needle is inserted correctly, if it's bent or dull, or if the threading is correct.
• Thread Breakage: Inspect the thread path for obstructions, ensure proper tension, and check for burrs on the needle or machine parts.
• Uneven Stitches: Verify correct tension settings for both upper and bobbin threads. Ensure the presser foot pressure is appropriate for the fabric.
• Machine Not Starting: Check power connections, ensure the motor switch is on, and verify the V-belt is properly engaged.
• Physical Damage: Upon receiving the product, inspect all components for any shipping damage. Contact your seller immediately if damage is found.
