Could loopers have been damaged on my Huskylock 936 for having wrongly threaded my left needle on the upper left chain needle thread guide& My serger after stitcking for a while did start with a bang sound and it sounds like loopers were banging on the left needle?

    Could my Huskylock 936 overlocker from Husqvarna Viking timing have been unsettled being I wrongly did thread the left needle while overlocking on a 4-thread overlock stitch? I did mistakenly pass the left needle thread on the upper chain thread path guide instead of the lower path guide for the left needle overlock stitch. I did stitch with the wrong threading for a while then there was a tuck, tuck on the machine as if the needles were banging on the loopers. Could the loopers have been damaged or the machine having been put out of timing ? My repairman says that it will be costing over $200 for time repair and some parts being changed? Is this too costly?
    Many thanks.

Unfortunately yes, it may have caused misalignment and caused it to bind momentarily, and this may cause damage indeed.. It is a little unusual, but some machines are very delicate and tolerances are finely setup. You most likely need it looked at by a professional.

-Carefully watch the loopers as you turn the wheel to see if the lower looper is rubbing or catching on anything.
-While turning the wheel do you see a tension point where the thread is pulling?
- Is the thread old? Thread has a shelf life and can get old and brittle. Change the threads around just to make sure.
- Have you "flossed" the thread through the tensions when you threaded them to make sure they are seated properly in the tension disks?
- Is there a bur or "pinch" in the threading areas that is catching the thread. Gently pull the thread back and forth at each location to see if anything "grabs" at the thread.
- Have you cleaned it and kept it dust free? Sometimes lint can build up in strategic locations and cause problems. Use a lint brush and canned air to remove lint. (Make sure you use the canned air to blow away from the machine as much as possible instead of into the machine.)
Check out f screws holding both lower and upper looper are loose or tight.If all the things checked out proper then its quite possible that the loppers have gone bad and it needs replacement. Get it replaced. Upper Looper:
Basically when the needles are at their highest position, the upper looper should be underneath the needles if you are looking straight on, but slightly in front if you are looking from above. ton the sample machine the looper should be 1mm in front of the needles.
Lower Looper:
The lower looper seems to belong exactly horizontal.
When the needles are at the lowest point the lower looper is supposed to be a certain distance from the left needle, for the sample machines it was 7mm. The needles do pass between the little pinchers in front of the looper.

When you rotate the handwheel the lower looper and upper looper's will pass very close to each other, they almost seem to fit together like a puzzle. There is probably a specified distance for this as well.
Finally it is important to remember that when you thread the machine the thread that goes through the lower looper lies on top of thread that goes through the upper looper. If you thread the machine and you can't get the lower looper thread above the upper looper thread then its not going to work.
Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

936 Huskylock needle bar does not move up and down.


First, make sure the machine is engaged to sew. some machines,
have a knob inside the flywheel on the left side that disconnect the sewing mechanism to wind a bobbin without the needle bar moving.

Husky lock 936 cover stitch troubleshooting


try a new needle

try rethreading that one needle

rethread the looper

if that doesn't help, then the machine may have a timing problem and would have to be checked

No chain forming on 1034d


You may have re-threaded in the wrong order. The correct order is upper looper, lower looper, right needle, left needle. So 3,4,2,1 (if numbering left to right)

Huskylock 936 coverstitch will not form stitches


I just went thru the EXACT same thing, pulled up YouTube videos and discovered it was all about (1) how the LOOPER was threaded (the video taught me it is called "the puppy dogs head/ears" and that to thread it you follow the path of the ORANGE DOT (which often is combined with either blue/black, but just look for the ORANGE dot path no matter what the other color is with it) and that thread goes: "Around the puppy dog's neck and behind his ears". Honest to God this was part of my problem. (2) TENSION settings: I also discovered that even though the 936 has the adviser has all recommended settings for the stitches, you still NEED to tinker with the tensions. Specifically, I was set up for the WIDE COVERSTITCH to hem a knit skirt. I selected the KNIT MEDIUM (Auto M4) stitch and used these tensions: A needle 4, E needle 6, Looper was ok at 3. It worked like a charm and FINALLY I can do the stitch! Seriously, there are many YouTube videos (many lousy quality) that actually show and explain this stitch and how to set up your machine. Hope this helps!!! Good luck and happy sewing!

I have a Huskylock 936 Serger and used it last week, no problem. I changed the threads for a new product and one thread came out and had to rethread. I know you have to thread the upper looper first then...


Recommend you remove all the threads and rethread from the beginning. ALWAYS RAISE THE PRESSER FOOT when threading and thread the upper looper first, the lower looper second. Sergers sometimes are temperamental about threading. When in doubt, start over from the beginning.

My Huskylock 936 - needle won't go down. The motor seems to be binding up.


Check your threading, both top and bottom, sounds like you have threaded wrong.

Needles hit the arm when stitching


Make sure you have completed all the steps to convert to cover stitch. There is a "clutch" to move from S to C for coverstitch that is located on the inside front of the machine where you thread the lower loopers. Make sure you have "locked down" the looper as instructed. There is a VHS and a DVD available from the Husqvarna Viking dealer. 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.

Huskylock 936 error code


This will also occur if the "needles" and "loopers" lock up as though threads are tangled and binding the machine. If needles and loopers move freely when manually turning the handwheel counter clockwise, you probably need 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.

Threading an Empisal Overlocker - Model S4D


All sergers thread the same way and sergers have to be threaded in a certain order. I made a jingle out of it...
upper looper
lower looper
right needle
left

It would be best to have a tweezers handy to help with the thread and threading.

always be sure the lower looper thread goes over the top of the upper looper then out the back. I would be surprised if your thread guides are not color coded.
If you look at the top thread guides or the spools. First from left to right thread the 3rd spool, then the fourth spool. Then you thread the right needle (the second spool) then the left needle (1st spool.
The lower looper can be tricky because you have to thread it from the back of the looper to the front.
Pull the threads out the back from under the foot. Then go ahead and run it slow watching to see if it starts making a chain. It should. If not do it over again.
Good luck

Threading a husqvarna huskylock 1001L serger


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.
