Hi, the tension on my sewing machine doesn't seem to be working. I have it all the way to 9 and the bottom stitch is still a little loose. Any advice?

Tensions on sewing machines really shouldn't be messed with at all, your problem is you don't have the machine threaded correctly nor the thread seated in between the tension disc. Turn your tention tunb back to between 3 and 4 and this should correct the problem

Loose stich on bottom of fabric

Hi. The problem is that your upper tension is too loose. It needs to be tighter in order to pull the bobbin thread up.

Needle timeing is out

The timing is set at the factory. If the threads are not hooking together, then perhaps try one of three things.

1. remove the thread, and run the machine at full speed for three minutes or more. This warms up the hardware, loosens gelled up oil, and get's all the parts in allignment.

2. (and 3.) Check the thread tentions. On the top thread, it will be a dial with numbers, over a spring and two plates that the thread runs through. On the bottom, it's a tiny screw on the side of the casing that the bobbin sits inside.

If the machine sews loose threads, then tighten these, a bit at at time, and if the machine jams up with a knot of thread at the needle, then loosen these. I believe that if the sewn threads are loose at the top, the bobbin tention neeeds tightening, and if the sewn threads on the bottom are loose, then the top tention dial needs tightening.

Simple solution..
take the thread off your machine, set your tension to the middle setting. rethread your machine up to the needle. before threading the needle, put your presser foot down. If your thread pulls hard, then the machine is threaded right. If it pulls easily, you need to chead the thread thru the tension wheel.

Rule of thumb.
Loops on the bottom, problem on the top.
Loops on the top, problem is on the bottom.
