Securing the upper blade

Switch off the electrical power

It is recommended to secure the movable 
upper blade 

23

 before sewing heavy fabrics. 

Raise the needle(s) to its highest position and 
open the swivel plate. Tighten the screw fully 
using the Allen key. This screw should always 
be slightly loosened again after sewing heavy 
fabrics.

Note:

The seam width can no longer be adjusted 
once the upper blade is secured.

Setting thread tension

The following pages contain directions for setting thread tensions for all programs. Adjust 
the tension by turning the tensioning wheel until the dot marker is at the desired setting.

The settings for adjusting thread tension are recommendations. Fabric type, thread quality 
and needle gauge will infl uence seam results. Always sew off a test seam onto a piece of 
scrap fabric and check the thread loops. Adjust the thread tension if necessary.

Adjusting the tension settings is described on pages 46 to 56.
