SEWING MACHINE TROUBLESHOOTING GUIDE
In most cases poor sewing results and breakdowns are caused by
three main factors:
1. The condition of the needle.
2. Threading and the quality of thread being used.
3. Mechanical breakdown or damaged parts.
The condition of the needle is the most common problem. Bent or
damaged needles will cause many different sewing problems. The
way the needle is inserted into the needle clamp is also very
important.
On most machines you install the needle so the flat is to the back of
the machine. Side load machines (bobbin case is inserted on the left
side of the machine) the flat is to the right. On some older Singer
machines the flat is to the left. The needle should be inserted flat to
the back on your machine.
Thread quality and the type of thread being used can be a problem.
Always use good quality thread and try to avoid thread that is old or
knotted. When ever possible use the same thread in the top and
bobbin tensions. Thread the machine as shown in your manual and
make sure the thread is between the tension discs.
