IN NEED OF A COPY OF THE USER MANUAL FOR THE HUSQVARNA VIKING 5610

All About Needles

...

Hard to explain here. You will probably need pictures to show you exactly. If you don't have the user manual/guide, it should be available on the husqvarna viking website under 'Machine Updates' (bottom right hand corner of home page). From Machine Updates page, select All machines and scroll down until you find your machine listed. Also most viking dealers are familiar with this machine and should be able to help you thread it if you stop by their store with the machine. You can find a dealer near you by using 'Locate a Dealer' link at the husqvarna viking website

Check this link out, it might be what you are needing?
