Remove the front cover and retrieve the spring. Re-install then good to go.

Thank yo so much for your videos, I have had my Jack F4 for a year now and there isn't anything in English out with this information. I love my machine but have questions...I think my pressure foot tension is to high as when i sew on quilting cotton it leaves dog feed marks on the fabric. Thank you thank you thank you!! Would love to see the Jack walking foot in action too!!

Your my go to guy for this machine. Thank you so much for your videos they have saved me a fortune. If possible could you please do a video for the a5e needle bar change as the one I bought has the wrong needle bar in it and the people I purchased from are absolutely no help at all. 😀

@@twisteddolldesigns6190 they take a DBx1 needle that has a 1.6mm top. Firstly I would suggest cleaning/clearing the needle hole using an old DBx1 needle. Loosen needle screw enough so you can fully insert the needle, maximum needle insertion can be checked through the hole in the side of your needle bar, then using a pair of long nose pliers gripping the needle repetitively insert and remove the needle, essential clearing or reaming the needle passage way, hopefully if all goes well, this will slowly become easier as it clears. Secondly always use a top quality needle like Groz Beckert, Schmetz (now Groz Beckert), or organ, cheaper needles are not manufactured to the best standards and may cause issues because of this. On a side note, if you want to use heavier threads, order system 71x1 needles, these go to a #160 size, and fit perfectly to your machine. Good luck.

@@ozcommercialsewingmachines thank you so much for the ideas, I've done all that you have recommended and i only use the brands organ and the schmetz needles aswell, still have to use the pliers to get the needle in, the size of the actual hole for the needle to go into is extremely small?? I'm so confused with it lol.

@@twisteddolldesigns6190, it sounds like the needle bar hole has an irregularity inside, very unusual, but of course it is possible, I would say it is around the area where the needle clamp screw goes in, the hole is very small, only 1.6mm, I believe it will free up over time.

Thank you for the video and it was very helpful and I'd like to know where I could get fixed when I needed. I find it's very hard to find supplies or to get services and even the person who sold it to me wouldn't want to see me again 🙃 😕

Unfortunately not but you can buy these from any good industrial sewing machine supplier as they are always breaking when you bump them.

How do I know what pressure for each fabric.there are no numbers on my new screw and nut I replaced.

You would need to experiment with different pressures as different thicknesses of fabric will have different pressure requirements.

Where can I order this part? Mines broke off and its stuck inside, after watching this video, I can fix it myself. Thanks

You will need to contact your closest JACK dealer, the broken part should wind out easily.

It sounds like you may need a visit to your local technician to do some fault finding.

Mine doesn’t have any numbers on so, what is the height from base if machine to top of the screw.

@ozcommercialsewingmachines

10 ай бұрын

You will need to determine what pressure you need based on the fabric you are sewing. Different fabrics and different thickness will all require different pressure so you will be adjusting to suit as you go.

Thank you so so much❤❤

There are only 2 things i dont like about the Jack machine. This foot adjuster feature is plastic and so is the manual foot lifter. Since the rest of the machine is so robust, I'm puzzled why they choose plastic.

@ozcommercialsewingmachines

These plastic parts are featured on most industrial machines these days.

With the presser foot you adjust the pressure, there is no tension on the presser foot.
