For best results your machine should be serviced before every large
project. This will increase the life of your machine and give you
problem free results when sewing.
Here is a checklist we have put together for your type of machine. If
you have problems while you are sewing run through the list to
correct the problem.
POOR STITCH QUALITY
1. The needle is incorrectly inserted. Check that the flat of the needle
is to the back of your machine.
2. The needle is blunt or bent. Your needle should be changed
before each large project or if it hits the needle plate or hook. A
damaged needle can also snag most fabrics.
3. The tension is not correct. The top tension of your machine should
be set to the red or centerline for regular sewing. Make sure the
thread is between the tension discs. Make sure the pressure foot
is up when threading your machine. (this will release the tension
discs) Check for lint or thread caught in the discs.
4. Type of thread being used can cause problems. Always use good
quality thread. When using heavy thread in the top you will have to
use a larger needle. The groove in the needle must fit the thread.
UPPER THREAD BREAKS
1. Check that the needle is inserted correctly and not damaged.
Check size of needle for thread.
2. Check your threading. There should be free movement of the
thread from spool to needle.
3. Make sure the top tension is not too tight.
4. Check the needle plate for damage.
5. Check the hook for damage.
