Your hook/needle timing is off and it needs to be seen by a technician before you damage the hook. Some dealers can do a 24 hour repair for an additional charge.

Hi, actually I can help with your problem but maybe you can help me with mine. A friend gave me the same model...without the instructions. Would you be willing to give me a pdf scan or photocopy of the manual, please? Let me know at [email protected]. Thanks!

Is the needle all the way up in the holder? Have you checked the timing with the bobbin and the needle. Look in your manual for needle timing

Also note that using a red band Singer needle will cause this exact symptom. The Singer needle is about 1.5 mm too long for use in any other machine. Ensure that you're using a standard needle. (Schmetz and Klasse are good examples.)

Your machine may also be out of time, which would require professional repair.

If the needle hits the bobbin case the are only 2 things that could be wrong. Lets hope its the easy one, there are more than one length of needles, if the needle is to long or it is not all the way up in the neelde bar, the needle will hit the inside of the bobbin case. Now if that is not the problem then the machine is out of time. ALWAYS check the easy stuff FIRST.
