Instruction for 20 GB early edition manual i lost mine given to me by my daughter in law many years ago.

Copyright laws don't allow copying the instructions and posting them online. But I can suggest re-buying the pattern (I found some on Etsy for as little as $3.99) or buying a similar pattern when Hancock or another fabric store has patterns for cheap. (They frequently have pattern sales for as little as $1.99.) An alternative source could be your local Salvation Army store, as many have older patterns--it doesn't have to be your exact pattern, just a similar looking layette pattern. The layette patterns should have similar sewing instructions, as long as the designs look similar.

Totally confused me with the explanation but I think I know what you are hetting at, the plastic bobbin sits flat in the bobbin case which should be black and the bobbin should turn anti clockwise in the bobbin case, contact [email protected] for a manual

Hi
I couldn't find a manual for the machine you mention but I did find one for the MyLock 204D. It is a Janome overlocker and may be very similar to your machine.

I found a free pdf manual for my 20 year old White serger at singerco.com. Hopefully you can find yours too.

Novum is made by Janome, if you haver a main dealer for Janome or New Home you can get the controls quite easily.

this link will take you to the sew cute page at white sewing, you can then find a dealer near you, perhaps they would photo copy a set of instructions for you

I think #39 on this link is the presser foot lever.

If you're looking for the foot control, that is #16 on the first link.

Whats the make and model no of the machine, can u please give some deatils

Check for a thread jam in the bobbincase. Lower looping is most commonly caused by a lack of top tension. Raise the presserfoot and rethread themachine again. Once threaded put down the presserfoot and pull the thread through the needle. if it pulls through easily it is still not threaded correctly. When threaded correctly the needle should bend but not break when you pull the thread through. good luck.
