How to do a Rolled Hem: Merrylock 740DSA

Parts of my Merrylock 740DSA manual is missing, the pages for doing a 3 thread rolled hem are not there. Now I can say with confidence that using the Merrylock 2020 manual I downloaded (address in post below) has been a great help and very useful. Because now I can do the 3-thread rolled hem and I'm so pleased with myself. Although I  will need to fine tune it, perhaps by using different thread, the one I'm using is weird...funny stuff! Or maybe I need to change my needle!

Instructions for rolled hem on the Merrylock 740DSA

The pages that you need to know about for making a 3-thread rolled hem stitch in the Merrylock 2020 manual are page 30, 37 and 38. Page 30 gives you a handy reference chart and if you look at number 7, it shows you the needle position and tensions, then refers you onto page 38.

On page 37 titled 'How To Sew A Rolled Hem' it gives you ideas as to what fabrics work best. Then further down the page you have 'Machine Set-up' and it tells you to remove the left needle and so forth.

When looking at page 38 you will see the tables for needle position, stitch length and tension dial numbers. The instructions are very clear and they have worked for me. I can do the 3-thread rolled hem. Except I probably need to play around with the thread plus tension (I saw some odd loops), but the stitch is definitely passable.

I didn't take the needle out I just unthreaded it...I knew
 I had to put it back in so I couldn't be bothered.
Very simple to switch over...
