Question about Singer 7470 Confidence Sewing Machine
It was working fine, then all of a sudden it stated catching the material & the needle kept dragging, now it won't work proper. I never touched anything, I just pulled it out of the box and stated using it as is. It came with a needle already in. The screw was so tight on the needle I had to use pliers to loosen.

SOURCE: Bobbin problems
Any time you have looping on the bottom, it is almost always related to the upper tension and not anything in the bobbin area.
A good way to troubleshoot this is to turn the machine off, blow out the upper tension disk assemblies with canned air, (the machine needs to be off because most canned air uses butane as a propellant. Butane + electricity = bad;) replace your needle, and rethread your machine. Once you've threaded it to the point where you're about to put the thread through the needle, "floss" the thread forward and backward to ensure that the thread seats correctly into the tension assemblies.
Set your tension to around 4.5 for most applications, and drop your presser foot. Give the thread a gentle tug to see if the tensions have engaged the thread, then thread the needle.
If doing this does not address the problem, you probably need to have your tensions professionally calibrated. This is also true if the needle is in fact hitting something in the bobbin area. This is usually caused by the machine's timing being out of alignment, which is not something that can be fixed at home.

try sewusa loads of manuals and sewing diagrams. Since its a older machine.I would clean and oil it also.Lint can cause all kinds of issues.

Have you changed the needle since you purchased it? A needle should be replaced every 4-6 hours of stitching so for each garment sewn as a rule of thumb. So try replacing the needle, cleaning and oiling the maachine as per the manual. Check needle is in the correct way, it is easy to put in backwards if you aren't familar with them, flat shank to the back and there is usually a scarf (cut away area) at the back of the needle which is where the rotary hook under the needle plate comes around to catch the upper thread during the stitch process. So if needle is in backwards this will cause stitching to fail.
So elimate the needle firstly.
If this fails and the knocking noise continues, then it could be that the timing has been knocked out. It can happen if you sew over a pin and hit it hard (or the needle strikes the foot if stitch setup is wrong for the foot being used). In this case, you'll need to take it back to the shop for the serviceman to fix.

Sounds like your machine is off timing, When the machine is properly timed, you should see the hook passing behind the eye of the needle when the needle is on it's upward stroke. If this is not correct the machine will not pick up the bobbin thread. You may have to take it in for adjusting, unless your a bit machnical.

Testimonial: "Thank you so much for your prompt and thoughful assistance. I would definitely recommend your service to others."
first change the needle--flat side to the back of the machine, make sure the needle is inserted all the way up into the needle holder
make sure it's the correct needle for the machine
if the needle keeps hitting the bobbin plate then the machine may be out of time & would have to be take to a sewing machine shop for retiming.
