Be careful to match needle and thread
• The thread should travel smoothly down the long groove • See instruction

«Important facts about thread and needle»

Working with the Double needle
To achieve the best sewing quality:
1. Upper threads must be guided separately into the thread guide of the needle 
clamp. At that point, thread the first thread behind the wire as usual (red arrow), 
thread the second thread in front of the wire. (picture 1)
2. The recommended optimal speed for Double Needles ranges from about  
350-500 stitches per minute. Set the slide speed control as shown below.  
(picture 2)
3. Make sure that the threads are not twisted after the thread take-up lever. For a
better sight the cover can be removed. 
As a general guideline: Replace the needle before starting a new sewing  
project. Needles are wearing parts and by frequent use they change their features. 
Even after 1.5 hours of useage first abrasions are recognizable. After about 8 
hours, increases in thread breakage, loops and poor stitch formation may occur.   
 

• Sew a test sample to find the optimal machine setting • Use a  
130/705 H-SUK/90-100 needle • Turn off automatic thread cutter to avoid excessive 
wear • Reduce upper thread tension (lower number) • Reduce motor speed and 
use thread lubricator
    
Radial feed of upper thread 

For best feed with certain thread types, a radial feed is suggested. Two options are 
listed: 

   

1. With smaller spools and/or loose twist: use the thread guide in the divider.  
(picture 3)  

 

2. For threads with a strong twist and/or larger spools (especially Mini-King): guide 
the thread around the telescoping guide directly into the side of the sewing  
computer. (picture 4)
In each case, a foam rotary disc must be used. To center the Mini-King spool 
always use the center aid. (picture 5) Thread lubrication can be used if necessary. 
(picture 6) Before starting, make sure that the thread between spool and thread 
guide of the sewing computer is slightly taut.
Radial feed, thread lubrication and thread guide can effectively increase the thread 
tension. Adjust upper tension setting as needed.

• The sewing computer must be switched on • See instruction manual chapter 
«Threading» and «Manual threading» • Various animations and videos may be 
viewed at: www.bernina8series.com/US/testdrive 

 

 

 

Always use one of the provided spool nets. This net prevents thread breakage 
when the thread gets caught at the edge of the spool.
• Use the white spool net with larger spools • Use the red net with smaller spools 
• Before threading automatically, always pull a small amount of thread out of the 
spool net
    

• Select and attach the correct presser foot according to the desired technique  
• Activate the presser foot indicator in the display and confirm the selected presser 
foot
The sewing computer can now make the necessary adjustments (e.g. Zipper Foot 
No. 4: the center of the icon in the display is gray = the needle can't stitch in this 
area).
