01Troubleshooting guide
How to wind a bobbin evenly
Winding is a separate operation from installing the bobbin. An empty, compatible bobbin and the model-specific winding path prevent loose or distorted layers.
02
Most likely causes
- A different bobbin class or a damaged or partly filled bobbin is being used.
- The thread has missed the bobbin-winding tension guide or is not seated between its discs.
- The bobbin is not fully seated on the spindle or the spindle has not reached its winding position.
03Step
Check in this order
- 01Step 1
Check the model manual and use an empty, undamaged bobbin of the specified class and material.
- 02Step 2
Lead the thread through every bobbin-winding guide and tension disc in the direction shown for the machine.
- 03Step 3
Place the bobbin firmly on the spindle, secure the thread end as instructed and engage winding mode.
- 04Step 4
Wind a few turns, stop to trim the loose tail when the manual requests it, then continue at a moderate speed until the automatic stop or stated fill level. Return the spindle to sewing position.
04
What should restore normal sewing
The thread should form firm, parallel layers without a cone shape, loose loops or bulging sides.
Install the bobbin only after confirming that it turns freely and is not overfilled.
