7 // THREAD TENSION
For an even stitch you also have to achieve an optimal foot
pressure. This means as soft as possible, but hard enough that
the material doesn‘t shift.
In this case the foot pressure is to light.
You must tighten the foot pressure.
In this case the foot pressure is too high.
You must loosen the foot pressure.
1. Loosen the lock nut. (1)
2. Turn the adjusting screw (2), to loosen or tighten the
pressure on the presser foot. Turn the screw (2) clockwise
to tighten or anticlockwise to loosen the pressure.
3. Tighten lock nut (1) after adjustment.
7/4 Setting the thread end length from the needle after cutting
The upper tension opens when the tread is cut. The tension is
only conducted by the pretension (1).
1. The standard thread length for the upper thread, after
cutting is 35 to 40 mm
2. You must raise the setting on the pretension to shorten
the rest thread length on the needle. When you reduce
the tension the rest thread length will be longer.
