Husqvarna Viking Ruby Royal Repair manual

To slow down the stitching speed on your Husqvarna Viking 18 x8, you can try the following steps:

1. Check the machine's manual: First, consult the manual that came with your Husqvarna Viking 18 x8 machine. The manual should have instructions on how to adjust the stitching speed.
2. Adjust the stitch length: One way to slow down the stitching speed is to adjust the stitch length. A shorter stitch length will slow down the machine's stitching speed. Refer to your machine's manual for instructions on how to adjust the stitch length.
3. Change the foot pressure: Another way to slow down the stitching speed is to change the foot pressure. Reducing the foot pressure can help slow down the machine's stitching speed. Again, refer to your machine's manual for instructions on how to adjust the foot pressure.
4. Use a different presser foot: Some presser feet are designed for slower stitching speeds. You can try using a different presser foot to slow down the machine's stitching speed.
5. Use a speed control pedal: Some machines come with a speed control pedal that allows you to adjust the machine's stitching speed. If your machine has a speed control pedal, try using it to slow down the stitching speed.

If none of these steps help slow down the stitching speed on your Husqvarna Viking 18 x8, you may need to contact a professional technician for assistance.

Did you adjust the bobbin tension first? Sewing machine tension is a delicate tug of war between the bobbin holding onto the bottom thread and the top tension pulling it to the centre of the fabric.

The 8:51 video is the best one that explains and shows how to do it.

The problem is that instruction for machine repair are pretty specific to the brand and model. For instance the two videos below are for Husqvarna Vikings but not necessarily for your model.

But first, here is a page which may direct you to corporate support for the machine:

Bear in mind that sewing machine mechanics usually repair machines! Elsewise, like with pocket watches, you may end up with more parts outside the machine than in the machine.

Here is a link to the user manual for your machine.

I am presuming that the reverse button is simply not stuck.

The Husqvarna Designer Ruby can read a number of embroidery file formats: .SHV, .DHV, .HUS, .VIP, .VP3, .PEC, .PCS, .SEW, .JEF, .EXP, .10*, and .DST. One other embroidery file format is accepted. See the manual. It can read the .SH7 stitch format files and .VF3 embroidery font files. It can also read .HTM/ .HTML and .TXT files. With the complimentary 5D software (or a similar package), you can convert most other embroidery files to one that is compatible with the Designer Ruby.

The documentation for many Husqvarna Viking sewing machines is available here: http://www.husqvarnaviking.com/Support . The manual and other useful information for the Designer Ruby is here: http://www.husqvarnaviking.com/support/DESIGNER-RUBY . The current link to the manual is http://www.husqvarnaviking.com/SiteMedia/Products/Machines/Support/Designer_Ruby_manual_ENG_A.pdf?ext=.pdf . The file extensions are listed on page 9:2 (page 100 of the PDF).

I hope this helps.

(I will admit to mostly using the .HUS files with the Designer Ruby.)

FWIW, I was unable to find any information for turning off the thread portioning function. Unfortunately, this appears to be the thread tensioning system, so disabling the thread portioning would be disabling the thread tensioning--something that is critical to sewing. It appears this model may have some issues and perhaps this one is particular to your machine. It may be best to take it for service.

Perhaps this will help:

I would go directly to the mfg and see if they have a troubleshooting page or a teck that can help

Check that the machine will turn freely by hand. It may still be jammed.

Here's a link to the foot pedals one company offers:

Maybe you can use their generic foot pedal listed at the bottom.

Try ebay or contact your local authorized Husqvarna Viking dealer. You can find a local dealer from the Husqvarna Viking website - http://www.husqvarnaviking.com/us/

your foot controller is damaged and should be replaced.
