You put one drop of oil in any joint that has a hole in it, or anything that slides or pivots.

Elna 410 450 Instruction Manual

Download the instruction manual for your machine free at the Singer Sewing Machine site. It will tell you how to do that.

it sounds like you need a new pattern selector dial & it wouldn't
hurt to have the machine checked to see if the internel part of the
dial is ok inside

i have same machine, you know i found that to be odd too. heres what you do, click it to the letter you like the style, then start sewing on a swatch at the very shortest stitch. then start increasing the stitch width more and more, up to 4 and see how it difers. i think thats where you will see the difference. i haven't played too much with mine yet, but listening to you is encouraging me to play on a swatch with all the difffernt styles you can stitch.

I am also looking for the user guide/ manual for the Elna Contessa 410. I saw Ana B's response and was hoping she could help me, please. email [email protected]

Here's what the manual says:

Before sewing, fit the button-hold foot to the machine (long white plastic thing with red, ruler like markings).

Select the pattern selector dial that is solid green on the left hand side. Set the dial to "1" position. Sew the left side and raise the needle.

Select the pattern selector dial that is solid green on the top and bottom. Set the dial to "2" position. Sew 5-6 stitches and raise the needle.

Select the pattern selector dial that is solid green on the right hand side. Set the dial to "3" position. Sew the right side. Raise the needle.

Select the pattern selector dial that is solid green on the top and bottom. Set the dial to "4" position. Sew 5-6 stitches and raise the needle.

Hope that helps...

I have a Elna Contessa 710 Manual. If you think it will help I may be able to scan a copy and email it to your own email address. Plz supply email address if interested or still unable to thread machine.
