This machine is equipped with the patented fine tuning feature mtc.
mtc provides easy controlling of the amount of the overedge thread along the fabric edge.
Always start at neutral position (center) when threading the machine to a new stitch con-
figuration. After the thread tension balance has been found, the amount of the overedge
thread can be fine tuned with the mtc thread control.
⦁
If the thread is firm and the fabric curls up (A), move the mtc thread control away from
the needle in (+) plus direction (2).
⦁ If the thread at the edge is loose (B), move the mtc thread control towards the needle
in (-) minus direction (3).

3 mtc-Thread control (-) minus
The mtc is the most effective in the range of 6 - 8 (Cutting width indiator).
With the knife position 5 - 6 the adjustment in (-) minus direction is limited.
With the knife position 8 - 9 the adjustment in (+) plus direction is limited.
The function of mtc is not guaranteed at stitch lengths longer than
3.5 mm.
For easy operation adjust the presser foot pressure only with lowered pressure
foot.
For most sewing projects the presser foot pressure may be left at standard setting M.
⦁ If adjustment is necessary, turn the presser foot pressure regulator.
