Trouble Shooting and FAQ

Industrial Sewing Machines:

Start with the instructions for your exact machine model. Switch off and isolate power as directed in the manual before changing needles, cleaning or checking moving parts.

  1. Threading issues:
  • Make sure the machine is threaded correctly. Refer to the threading diagram in the user manual or on the machine itself.
  • Check if the thread is passing through all the thread guides and tension discs. Make sure it is not tangled or twisted.
  • If your machine uses a bobbin, check that it is wound and inserted as shown in the model's manual.
  • Follow the manual's threading sequence, including whether to raise the presser foot when threading.
  1. Needle issues:
  • Match the exact needle system specified for your machine, then choose the appropriate needle size and point for the work. Insert the needle fully and orient its groove and scarf exactly as shown in the machine manual; the required direction varies by model.
  • Make sure the needle is not bent or dull. Replace it with a new needle if necessary.
  • Check the needle plate for any burrs or damage. A damaged needle plate can cause needle breakage or skipped stitches.
  1. Tension issues:
  • Check the upper and lower thread tension. Improper tension can cause thread breakage or stitching issues. Adjust the tension according to the user manual or based on the fabric being sewn.
  • For machines with a bobbin, follow the manual when checking bobbin tension. If an adjustment is needed and you are unsure, ask a sewing machine technician before turning tension screws.
  1. Machine issues:
  • Check the feed dogs for any damage or obstruction. Make sure they are moving freely and not jammed.
  • If you suspect a hook or timing problem, have a qualified sewing machine technician assess it. Use the model's service instructions for any adjustment.
  • Follow the model's instructions for cleaning and lubrication, using only the specified oil and lubrication points.

If the problem persists, ask about sewing machine servicing and repairs or contact us with the model number and a description of the issue. For a new needle, browse industrial sewing machine needles by system and match your machine manual before ordering.
