Does anyone know anything about this machine? The name on it is "Cosita". Done a lot of searching on the net and can't find anything, although one site did seem to link it to Pfaff. However, the Pfaff site has no info on the machine.
I've been given the machine and would like to give it an overhaul and start using it, but would really like to find the proper instructions on use.
Thanks,

Thanks DobbinDee...I've posted a query on the wefixit site. Here's hoping someone knows something about it.
Hi Marie,
It looks like a fairly basic zig-zag machine, probably Asian, with feed dog drop. You want the feed dogs in normal position for general sewing, mid for very light fabrics, and down for darning or embroidery or free motion work. Vertical bobbin with bobbin case? or drop in bobbin?
The stitch width is the horizontal lever in the middle at the top, the stitch length is the vertical lever on the pillar. It probably does reverse by taking the stitch length lever to the upper high position. For straight stitch you want the width at 0.
The thread path looks pretty straight forward 'down up down', start with a parallel wound spool on the right hand spool pin, and the wheel turned so the thread takeup lever is at the top - bring the thread across to the thread guide, down and between the tension discs, catch the spring if there is one, under the thread guide just next to the tension dial, up into the thread takeup lever, down to the needle. The key will be to have the needle set correctly - it will probably be self setting with a flat in the needlebar, for the flat of the needle shank to rest against. The threading direction - the opposite of the flat side of the shank - this is the side you thread from. The flat to the right, thread left to right. flat to the left, thread right to left. Tension setting - righty tighty - lefty loosy - play with it until you get even stitches.
If you don't have any parralel wound spools of thread, use a crosswound one, but sometimes they tangle. Crosswound spools are designed to lie down.
To wind a bobbin - put the spool on the left side pin - bring the thread down to the little tension on the bed - wrap around once, and run the thread tail out through a hole in the bobbin side. Place the bobbin on the bobbin winder pin, turn by hand until it clicks into place, then press the bobbin pin down till the ring engages on the wheel. There should be a centre knob in the middle of the balance wheel, loosen this to get the machine to wind the bobbin without the needle going up and down.
