How do you adjust the length - Sewing Machines

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:

You might need to Google "stitch length adjustment" for your particular machine (brand, model). However, here some pages with generic information:

Check for a user guide or a forum or tips on the maufacture's site, as well. You might even find a YouTube video about the suject.

Perhaps the manual will help:

A zigzag can be adjusted by the width and length of the stitch. If you start with a straight stitch it is easy to see what the length of the stitch will be. The width is adjustable. By adjusting the two together you can have a large choice of quality stitches.

To adjust the stitch length, press down on the plunger on the base of the machine. It's to the right of the needle and towards the back. While holding the plunger down, rotate the pulley until the plunger enters a notch in the the adjustable feed eccentric cam (visible on near the center back on the bottom of the machine). Then adjust the pulley forwards or backwards until the desired number of stitches per inch is visible in the stitch length window to the left of the pulley. Then release the plunger.

See page 14 of the manual which is available from Singer here: http://parts.singerco.com/IPinstManuals/111W152_W153_W154_W155.pdf . It's page 8 of the PDF. You will also need to look at Figure 2 on page 4. Figure 5 on page 4 shows the cam (J1) that the plunger enters when you can adjust the stitch length.

I hope this helps.

you might call a repair shop and tell them the problem and ask
them how much it would cost to have the machine repaired that
way you can decide.

take the machine to a sewing machine shop & have them check the screw
or the stitch length adjuster, the threads could be stripped out

since the dial won't move, the machine needs to be checked

Hello

Adjust the Stitch Length;

To make longer stitches, set the stitch length to a higher number. On many sewing machines, four is the longest possible stitch length and two is average.

To make shorter stitches, set the stitch length to a lower number. At a zero, the sewing machine may not actually make stitches, since the needle will go up and down in one place.

Cut a small scrap of fabric, preferably the same type you want to sew with.

Sew a few test stitches on the scrap. Examine the stitches to make sure they're the length you want.

Adjust the stitch length again as needed.

Sounds like it is either out of time or the adjuster spring needs to be replaced.
