Typically, a miss-start occurs when the machine starts the sewing process without grabbing the bobbin thread. Use the following table if you are experiencing miss-starts.

Possible Causes |
Solutions |
|
Tail length (length of thread tail left after a trim) may be set too short |
In AMAYA OS, select the Settings menu, then click the Machine Settings tab. Change the tail length setting to Medium or Long. |
|
Thread is not held in trap (in grabber assembly) during trims b/c the trap or grabber blade may be damaged or may not be adjusted correctly. |

Under thread presser (which holds bobbin thread after a trim) may be damaged or not adjusted correctly. The under thread presser is part of the trimmer system and is located directly under the adjustable fixed knife. |
The under thread presser needs to be inspected (you may find this easier to do if you remove the needle plate). Inspect the under thread presser to determine if it is touching the adjustable fixed knife (you may find this easier to do if you use a flashlight). If the under thread presser is not touching the adjustable fixed knife, it needs to be replaced or adjusted; contact Melco Technical Support |
