Common Problems and Troubleshooting for KPCB Tech FHSM-201

1. Thread Tension Issues

Description: Uneven stitches, loose threads, or thread breakage during sewing.

Cause: Incorrect thread tension settings.


  • Ensure the thread is correctly threaded through the tension discs.
  • Check if the tension dial is set to an appropriate level (generally around 4-5).
  • Experiment with different tension settings on scrap fabric to find the optimal tension for your specific fabric.

2. Jammed Bobbin

Description: The bobbin thread gets tangled or stuck.

Cause: Incorrect bobbin insertion or threading.


  • Remove the bobbin case and check for any tangled threads or lint.
  • Reinsert the bobbin with the thread unwinding in the correct direction.
  • Ensure the bobbin is correctly placed in the bobbin case and threaded through the tension spring.

3. Skipped Stitches

Description: Stitches are missing in certain areas of the fabric.

Cause: Dull or incorrect needle, improper threading.


  • Replace the needle with a new one suitable for your fabric.
  • Check that the needle is inserted all the way up and facing the correct direction.
  • Rethread the machine, making sure the thread passes through all the guides and the needle’s eye.

4. Uneven Fabric Feed

Description: Fabric is pulled unevenly, causing uneven stitching.

Cause: Incorrect presser foot pressure, improper fabric handling.


  • Adjust the presser foot pressure to match your fabric’s thickness.
  • Hold the fabric with gentle, even pressure while sewing to ensure smooth feeding.
  • Consider using a walking foot or a sewing machine extension table for better fabric control.

5. Bobbin Thread Not Catching

Description: The upper thread doesn’t catch the bobbin thread to form stitches.

Cause: Incorrect threading, bobbin insertion, or needle position.


  • Re-thread the upper thread, following the correct threading path as specified in the manual.
  • Ensure the bobbin is correctly inserted in the bobbin case and properly wound.
  • Check if the needle is correctly positioned and inserted.

6. Motor Running But Needle Not Moving

Description: The sewing machine motor is running, but the needle is not moving.

Cause: The handwheel clutch is disengaged.


  • Check if the handwheel clutch knob is tightened (usually by turning it toward you).
  • If the clutch is engaged, but the needle still doesn’t move, there might be a belt or gear issue. Consider seeking professional help.

7. Excessive Noise While Sewing

Description: The sewing machine is making loud or unusual noises during operation.

Cause: Lack of lubrication, foreign objects in the machine, or parts needing adjustment.


  • Clean the machine and remove any lint or debris from the bobbin area.
  • Apply a drop of sewing machine oil to the moving parts as indicated in the manual.
  • If the noise persists, consult the manual for maintenance or consider professional servicing.

8. Needle Breaking

Description: Needles are frequently breaking while sewing.

Cause: Using the wrong needle for the fabric, incorrect needle insertion, or hitting pins.


  • Select the appropriate needle type and size for your fabric (e.g., ballpoint for knits, universal for woven).
  • Ensure the needle is fully inserted and tightened.
  • Avoid sewing over pins and remove them before they reach the needle area.

9. Fabric Not Feeding Properly

Description: The fabric is not moving forward smoothly while sewing.

Cause: Incorrect presser foot pressure, worn-out feed dogs, or improper fabric handling.
