Brother XL3750 Mechanical Sewing Machine - Answered Questions & Fixed issues

contact brother customer service about the oiling.

Hello, Cwpetronio - I hope I am correct in thinking your Brother sewing machine is in the XL series of sewing machines. If so . . . I think you will find the instructive illustrations here helpful: http://support.brother.com/g/b/faqend.aspx?prod=hf_xl3750eus&c=us_ot&lang=en&faqid=faqh00000467_000 I would think the instructions for threading the machine are in the owner's manual. If you do not have the manual, you can download on free here: http://homeappliance.manualsonline.com/manuals/mfg/brother/xl3750.html Note: The manual is in PDF format, meaning you will need Adobe Reader software (free). After you download the manual, I recommend you save it in your Documents folder using a file name you can find again easily - Brother XL-3750 Manual. You can print the manual for easy reference. Best wishes.

Adjust needle timing. Look up on YouTube.com for sewing machine needle timing adjustment video. Easy to do.

you can download a manual for your machine from the Brother website,link ishttp://welcome.solutions.brother.com/BSC/public/files/dlf/doch000452/bm2736xl26i35i375ug04enes.pdfReverse is the big lever in front but it should be sprung so you need to hold it down to reverse; if your machine is only sewing backwards, this lever might be stuck or locked into position. Check out page 25 and 26 in the manual for specific info.

It may also be that the feed dogs aren't adjusted properly. It any case these adjustment are all internal and very difficult to do without access the the service/parts manuals. My advise is to take it to a Brother Dealer or service center.

Skipped stitches 1. The needle is not inserted correctly Remove needle & reinsert needle( flat side towards the back of machine) 2. The needle is damaged replace with new needle3. The wrong size needle is being used Choose a needle to suit the thread & fabric 4. The foot not attached correctly Check & attach correctly

have you tried rethreading the machine?have you tried a new needle?

try changing the needleclean under the needle plate for lint, flannel has quite a bit of lint make sure the bobbin is turned the correct way in the bobbin casetry rethreading the machine top & bobbin

it sounds like the machine needs to be serviced

the manual is downloadable from herehttp://welcome.solutions.brother.com/BSC/public/files/dlf/doch000452/bm2736xl26i35i375ug04enes.pdfbut it doesn't specify the weight. Shipping Weight (in pounds): 18.25 Product in Inches (L x W x H): 15.4 x 6.7 x 11.5

There is a pressure adjustment for the presser foot.

This is usually on top of the machine, over the presser foot.

If it resembles a screw head on this model - a dab of nail polish or mark of a sharpie will help when you reset after sewing sheer fabrics.

If you move the adjustment to the left it will reduce the pressure and should also reduce the wrinkling.

Adjust and then test on a sample of the same fabric you will be sewing.

Be sure to re-set after sewing thin fabrics.

Refer to the manual or download a free one at Brother's website.

Refer to the manual for cleaning the bobbin area and the recommended setting for the tension.

Thread the machine with the presser foot up and the bunching should stop.

If you do not have a manual you can download free at the Brother website.

It sounds as if you have a tension problem. Let me give you instructions for adjusting the tension on anysewing machine. Be sure to have a scrap piece of the fabric you are using andthread the top of the machine with a different color of thread than thebobbin-it'll make it easier to see what's going on. Thread your machine with the presser foot UP. The disks that control the tension (threadgoes through them) are tightened up if the foot is down. Change the machine tension with the presser foot DOWN.Because the disks won't be engaged (see above) if the foot is up, the diskswon't move. Start at the middle setting, 3. Go up to tighten, decrease toloosen. Each machine is different, even 2 different machines of the same model.The best thing to do is start at 3 and use a different color in the top andbobbin thread so you can easily see what changes to the tension do to yourstitches. Now use a straight stitch a sew 3 or so inches. Take a lookat the top and bottom of the fabric. You don't want to see any (or at least notmuch) of the other color showing from the other side. Loops on the bottom of the fabric means you need to tighten(increase) your top tension. If you're stitches on the bottom are causingpuckering, then you need to loosen you're top tension. For the most part, youreally don't want to touch your bobbin tension-leave that to a repairtechnician. The factory setting shouldn't be touched except by someone whoreally knows what they're doing. Keep sewing a few inches at a time until you have the resultsyou want. Now you're tension is where you need it!

Yes, if you set the number higher the tension is higher, but it's not quite as simple as that. Let me give you instructions that work for any machine. I suggest you thread the top with a different color thread than the bobbin-it's easier to see exactly what's going on that way.

This has to be done by hand.
Raise the presser foot, then thread all the way down to the needle. Put in the full bobbin with thread end loose and visible. Hold the end of the thread in the needle with one hand and carefully turn the wheel so that the needle lowers and lifts the bobbin thread. Place both threads behind the presser foot. Now you can sew.

How about using a tear away stabilizer or tissure wrapping paper? Sometimes the fleece is just to cushy for the machine. I would put some on the throat plate, and between the fabric and fleece, then tear it off. Good luck, I hope that helps.

If you threaded the machine with the presser foot up and the is bobbin inserted so the bobbin thread is feeding from the bobbin spool in the correct direction and through the guides as indicated in the manual, then there is a possibility that the timing needs to be adjusted by an authorized Brother tech.

try this, set the tension at 3, the width at 2.5 and the length at 2. this should give you a nice straight stitch for basic sewing or piecing for quilting.
