Stitching issues are often caused by setup or consumable-related factors rather than machine faults. Before escalating the issue, the following checks should be completed.
Common causes of stitching problems include:
Incorrect threading of the machine
Worn, damaged, or incorrect needle selection
Incorrect thread tension settings
These factors can affect stitch formation, consistency, and overall quality.
Before raising a support or warranty request:
Completely re-thread the machine using the supplied threading diagram
Replace the needle and any other relevant consumables
Check and adjust thread tension as required
Many stitching issues are resolved by completing these steps.
If stitching issues continue after re-threading and replacing consumables, contact AE Sewing Machines for further assistance. Providing details of the issue and steps already taken helps speed up diagnosis.
