How to thread a double needle on a Husqvarna, Platinum 715?

The bobbin/needle jam is often a threading issue. Rethread both and try again. If that doesn't work, let me know.

if your asking about sewing with double needles, then here is the answer. thread the 1st needle like normal,, then use the other spool pin to start the other spool of thread and then thread the machine the same way you did the 1st needle and then thread the 2nd needle and pull the thread tails behind the needles toward the back of the machine and you should be ready to sew.

Lower thread tension can be adjusted by tightening (clockwise) the small screw in the bobbin case. The specifications call for 12-20 g resistance when pulling the thread slowly. I suggest tightening in increments of 1/8 turn and trying the machine each time. Also, mark the position of the screw in its original position should you need to return to the original setting and start over (use a piece of tape and place a mark where the slot in the screw is). I don't understand what you're saying about the zig zag problem.

Hello

Install the second spool pin.
Place the two spools on the spools pins, one on each spool pin.Make sure that the spools are spinning toward each other.
Thread as for single needle.
Thread each needle from a different spool.
Caution: Make sure that the stitch width is not wide than the twin needle maximum swing. Check that the needles will not hit the throat plate as they swing from left to right and back again on stitches with width.

Happy twin needling

thread like normal for the first needle
now add a second spool of thead & thread the same path as the first
as the first needle only thread the second needle now

try changing the needle

Most of the time the bobbin case gets hung under the feed dogs, take your needle plate off and the bobbin cover there is a gray colored finger with a number 10 torx screw holding it in you can also try a small flat head screw driver, remove that finger and then remove your bobbin clean the hook out and replace the bobbin making sure it seats itself on the hook with the small notch on the bobbin case lining up with a small metall spring on the back right side of the hook area.

Sounds like the upper thread sensor has some issues. Since this is from 2008, assume the issue has been resolved. If it's not, you might want to take it to an authorized husqvarna viking dealer for service. You can locate a dealer near you by visiting the husqvarna viking website and clicking on the Dealer link on the left-hand side of the page - http://www.husqvarnaviking.com
Good luck.

DO NOT RESET THE TIMING!! The timing is off on maybe 1 in 100 modern Husqvarna machines. For the user to change the timing is turning a simple fix into a complicated and expensive fix.
If the top thread is "looping up on the bottom" then you have a problem with the tension on the top thread. Here is what to check:
1. Thread the machine all the way through the eye of the needle. Don't go under the foot.
2. Pull the tread to the side. While pulling, lower the presser foot. You should see the needle bend as the thread gets tight. If not, you have no tension on the top thread.
3. With the bobbin in the case, hold the needle thread and turn the handwheel to bring the thread up. Watch through the cover to see if the thread passes over the bobbin from left to right. When it gets to the right side, the take up lever should pull the slack out and the thread should be pulled up. If it comes part way across but does not pull up, make sure the thread is in the take up lever. If you never see the thread, remove the bobbin case and turn the hand wheel. You should be able to see the hook pass behind the needle while the eye is still below the level of the hook. If the eye is above the hook as it passes the needle from right to left, then and only then consider timing the machine. If the hook passes above the eye but doesn't catch the thread (bobbin case out, needle plate on, presser foot down) you probably have a problem with your needle. Put in a new needle and make sure that the flat side is to the back.
99% of the time when a Husqvarna is not picking up the bobbin thread, something simple has been overlooked. Your symptom of looping on the back of the fabric indicate either a threading or tension issue in most cases, not timing.

Solution taken from "Handbook for Huskylock Sewing Machine Models 1001L/1000L/1000"

1. Raise the presser foot by using presser foot lever. When the presser foot is raised, the two thread tension discs in the thread tension control panel are released so that thread passes freely between them. Otherwise thread tension may not be correct.

Important! When threading the needle, always be sure to lift the presser foot lever, and also take care to thread in the proper order.

Threading order:
1. Upper looper thread (green)
2. Lower looper thread (blue)
3. Double chain stitch looper thread (purple) in case of 5 thread stitch or double chain stitch
4. Right needle thread (red)
5. Left needle thread or double chain needle thread (yellow)

Caution!
Because the left thread tension dial (yellow) is used for either the left needle or the double chain stitch needle, these needles will never be used at the same time.

Upper looper (green) sequence:
1. Thread holder (silver triangle openings attached to thread holder stand)
2. Thread guide (flat silver clips just behind thread tension disc)
3. Thread tension disc (circular knobs with numbers for tension setting)
4. Pull thread around upper looper guide and upper looper
5. Pull thread into hole of upper looper

Lower looper (blue)
Repeat 1, 2, 3.
4. Pull thread around guide (see color coded chart inside front serger cover).

Easy threading mechanism (for lower looper)
1. Pull out the lower looper threading lever
2. Thread the lower looper and position the thread on hook of the lower looper
threading lever.
3. Push the lower looper threading lever back to its basic position while
holding the end of the thread.

Caution:
When returning the lower looper threading lever, always make sure that the two
blue triangle marks (directional arrows) meet each other.

Right needle thread (red)
Left needle thread (yellow)
Important: Thread the needles after threading of lower looper and upper looper.
First raise the presser foot lever, and then thread the needle threads in order shown in color coded thread guide.
