Need manual instructions for Riccar 2910 need help with bobbin, threding machined and tension setting and bobbin holder.

You may have a bent needle. Where is it hitting, front, back or side of the needle plate?

Check the model number of the machine. White sewing machine manuals are available from Singer at http://www.singerco.com/accessories/instruction-manuals . Enter the model number and click Search.

The White Sew E-Z model W338 manual is available here: http://www.singerco.com/uploads/download/705_white-338-x.pdf .

Unlike some machines this one doesn't really need the bobbin threaded. Place the bobbin in the bobbin holder and leave about 5" of thread extended out from the bobbin holder. With the bobbin compartment still open, lower the presser foot and turn the handwheel to move the threaded needle through the stitch cycle. (I find holding the threads helps; normally, you'll feel them pulling under your fingers.) When the needle has returned to the top of the path, lift the presser foot. Then pull both threads around to the front (the bobbin thread should wrap around the top thread). Then move the threads to the back of the presser foot.

If the needle isn't catching the bobbin thread, first try a new needle (bent or dull needles don't always function properly). Next check the bobbin holder for nicks or other damage. There is a small hook on the bobbin holder that should be where the top and bottom threads intertwine. Under rare circumstances, you will find that the bobbin tension of the bobbin holder is misadjusted. This can interfere with the bobbin thread twisting properly. There is a little set screw that allows you can tighten or loosen the bobbin tension as needed. Adjusting the screw is to be avoided when possible and done in small increments (1/8 turn) if needed. It's easy to strip the threads for the set screw and end up needing to replace the bobbin holder.

I hope this helps.

Check the bobbin tension and that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder.

Hi you can download free manuals from the Riccar site.
I think this is the one you need:

Hope this helps!

Here's a manual for the Riccar 2910, it should be similar to your machine.
http://www.riccar.com/ftp/whitepapers/2910-Owners-Manual.pdf
Threading is on page 13 and 14 of the manual, I think, Have a browse through it. Hope this helps!

This can be caused by several different things. Check the threading. Un-thread the machine and follow the guidance on the manual and re-thread the machine. The bobbin, if the bobbin thread that coming out of the bobbin case in a wrong direction, could cause this. Re-set the direction. When you pull thread from the bobbin case, bobbin should roll counter clockwise. The needle, if it is not the right size needle for the fabric or the needle is slightly bent, maybe replace the needle and try with different size of needle. Once its balling up, sometimes it's left some thread in the machine under the needle plate around the feed dog, clean them up. Thread tension, different fabric may need to be adjust the thread tension, try to check this one under the manuals/instruction. When ready, check and use a scrap of fabric/remnants!

this might work. i have the same machine and use metal bobbins

2925 uses the same needle plate as 2910 and that manual is available at Riccar.com as a PDF file. I could email that file as I just downloaded it.

insert bobbins to shuttle hook case under needle foot holder

lift the cover plate you can see under this is the shuttle hookafter set up was made on bobbins thread,set also the upper loop thead beginning at top of machine start on spool, pull thread and loop to upper disc tension then to the slot portion as in figure

insert on lever dial goes to the needle adjust tension to #8 range to #12 for cotton fabrics two layer sewing.
