5. Troubleshooting

If you encounter issues with your JUKI DDL-9000C-SMS, consider the following common solutions:

• Uneven Stitching: Adjust thread tension (both upper and bobbin), ensure the presser foot pressure is appropriate for the fabric, and check for proper stitch length settings.
• Machine Noise: While the machine is designed to be quiet, unusual noises may indicate a need for lubrication or inspection of moving parts. Refer to the full manual for detailed lubrication points.
