My machine model is necchi 802. Ilost my manual of it So please let me know how to adjust to stitch zigzag stitches?

If your Bernina 930 record sewing machine is experiencing issues with zigzag stitches and straight stitches, here are some troubleshooting steps you can try:

1. Check the needle: Ensure that the needle is properly inserted and not bent or dull. Replace the needle if necessary, making sure to use the correct needle type and size for the fabric you are sewing.
2. Adjust the stitch width and length: Verify that the stitch width and length settings are properly adjusted for the desired zigzag stitch. Refer to your machine's user manual for instructions on how to adjust these settings correctly.
3. Clean and lubricate the machine: A build-up of lint or lack of lubrication can affect the machine's performance. Clean the bobbin area and other accessible parts of the machine using a soft brush or lint brush. Apply a drop of sewing machine oil to the recommended areas as specified in the user manual.
4. Check the tension: Improper tension can lead to skipped stitches. Ensure that the upper thread tension is properly adjusted for the fabric and thread you are using. Consult the user manual for guidance on adjusting the tension correctly.
5. Test with different fabrics and threads: Try sewing on different fabrics using different types of thread to determine if the issue is specific to certain materials. This will help identify whether the problem lies with the machine or the materials being used.
6. Have the machine serviced: If the above steps do not resolve the issue, it may be necessary to have your Bernina 930 record serviced by a professional. There could be underlying mechanical issues that require expert attention.

It's important to note that the Bernina 930 record is a vintage sewing machine, and finding a qualified technician with experience working on older models may be beneficial if further repairs or adjustments are needed.

If you haven't removed the top to clean and oil the cams then likely they are stuck, hence zigzag.

Doing a google search for the brand plus model number for a user guide or YouTube videos might find what you are looking for. That it is a Necchi doesn't supply the model number and of course models differ. On a 537L model, the large knob on the right side about halfway between the top and bottom of the machine adjusts stitch length. The numbers may range from 0 to 5 with 0 meaning no length and 5 being the largest length. Tension, stitch length and stitch width are all controlled by small dials on the front of the Necchi machine. If your stitch length is set to 0, the sewing machine will not feed the fabric. Incorrect tension will cause poor stitch quality. You must consult you machine's user manual to know how to adjust the tension as the procedure differs among machines. Here is a general guide, however:

Yep, thorough cleaning and oiling.


Wheel on right side that controls the needle up and down is very tight...

Will not zigzag or decorative stitches New to these newer plastic style...

Hi there, don't know your machine but you can do a plaiin buttonhole manually.
Set machine up for zigzag stitch, needle to left side, mark out the size you need with pins or marker pen. Start at the top and set for widest zigzag with 0 length for the top bar, cannot give sizes as don't know the button you are using, about 6 stitches, set stitch width to just over half the width of top bar and length to approx 0.5. Stitch down to bottom marker and again set up ffor the wide bar, do the same amount of stitches as the top, finish with needle down at the outside edge, turn work so that you will now stitch down the other side to meet the top bar, not forgetting to adjust stitch length and width again.
Hope this helps

It's just in the front panel, where the drawing of all the built in stitches are, it's the drawing number eleven from the left, you'll see a zig zag (red) and a straight stitch (black) Select A group of stitches (knob with the arrow) and then select the eleventh stitch (same knob but use the dial, look the manual) and then select zero on your stitch width dial. Hope that helps :)

Hello! Hello!

Your machine is probably not 50 years old. I have one just like it that we purchased about 5 years ago. Necchi makes a very sturdy reliable machine. There are a couple of tricks, though. First, your bobbin thread has to turn clockwise. If it doesn't, it will either not sew, the stitch will look horrible or the thread will break. Second, threading it is pretty easy; however, I can't explain some of the parts. I would be happy to scan the diagram and e-mail it to you. E-mail: [email protected]. The tension should be set at 3 unless you are doing a ruffle or close zigzagging (machine applique). For applique, I find that I have to move it to 2. For ruffles or gathering, set it at 0 and your stitch width to 4. Another trick is to hold the top thread for the first 2 stitches. This alleviates a bobbin catch at the beginning. Other things you will want to know are in regard to the two knobs. One is pretty simple. It has a line that gradually increases in a zigzag. This knob basically adjusts the width of the zig zag. Obviously, for straight stitching, you would make sure the straight line is towards the top. The other knob determines the type of stitch you want to do. The red stitch options on top of the machine can be done with #1, 2, 3, 4 or 5 at the top; however, I usually use #1. The blue stitches are really fun! Simply decide which stich you want and make sure the corresponding number on the dial is turned towards the top. Also, it is very important that you adjust the other knob to the largest zigzag possible AND change the stitch length to 4. Don't pull on the fabric from behind the machine as you are sewing, because the machine will go forward and backwards while making many of these stitches. The green A, B, C on the dial are used for the automatic buttonhole feature. In order to use this, make sure you have the button hole foot. It looks like a long rectangular piece of plastic with measurements on it and hollow in the center. Not sure if that description makes sense. Anyway, the first step is "C." Make sure you begin with the button hole pressure foot measuring "0". Also, change your zigzag width to the desired width AND change the stitch length to less than 1. (You will notice that this area has a green line on it.) Begin stitching. You should be moving forward. When you have reached the desired length, make sure the needle is up, then turn the knob to "B" (sometimes I make my zigzag wider for this part), begin sewing. You should not go forward or backward. This step makes the bottom of the button hole. I only make 3 or 4 "B" stitches. When done, make sure the needle is up, adjust your zigzag back again if you changed it for B, and set it on "A". This will take you backwards. If you started your button hole with the foot on 0, it will automatically stop moving backwards when you reach 0 again. At this point make sure your needle is up again, then set the knob on "B" once more. If you adjusted B before, do it again. There you are! You can use twin needles on this machine. It also works well with a walking foot for quilting. Oh! To wind your bobbin (starting from the thread spool) you need to slide the thread under the little metal knob sticking out on top of the metal "?" right above the tension and then insert it into the hole in the bobbin spool. Push the bobbin to the right. This locks it into place. Next, hold the outer part of the flywheel (round wheel on right side of machine) while turning the inner wheel towards you. This will disengage the needle and allow the bobbin to wind. Now you can press on the "gas" and wa-laah. It will slow down and almost stop when it is completed. Cut your thread, slide the bobbin to the left to unlock, tighten the wheel and you're done. If you have any more questions, let me know. Hope this helps!

Either you have the setting on a variation of ZZ which steps forward several stitches then one to the side (ZZ), so check that first.

If you are certain it is on the correct ZZ setting, and this is a recent purchase, phone the dealer tell them the issue and arrange to take it back for them to adjust, it is almost certainly ever so slightly out of timing.

You probably have not adjusted you stitch width and length.
Also a manual for this machine is currently being sold on Ebay for $4+. Probably would be a good investment for you.
