WARNING
Risk of injury from moving parts!
Crushing possible.
Switch the sewing machine off before you remove
the covers or refit them.
In many types of setting work, you will have to remove the machine covers
first in order to access the components.
Described here is how to remove the individual covers and how to reattach
them. Just the cover that needs to be removed is then specified in the text
for that particular type of setting work.
3.3.1 Access to the machine bottom section
In order to access the components at the machine bottom section, you
must first tilt the machine upper section to the left.

Adjusting the thread regulator
9Adjusting the thread regulator
The thread regulator determines the needle thread quantity to be guided
around the hook. The required thread quantity depends on the thickness
of the material to be sewn, thread strength, and stitch length.
Larger thread quantity for
• thick material
• high thread strengths
• large stitch lengths
Lower thread quantity for
• thin material
• low thread strengths
• small stitch lengths
Checking the correct setting
1.Open the hook flap ( S. 17) and observe the thread running around
the hook:
The needle thread loop runs without surplus and without jumping
around the largest hook diameter.
Faults caused by an incorrect setting
• Poor sewing results
