... by turning the seam width adjustment knob

Setting the seam width adjustment knob
Attention!
Before making adjustments with the seam width adjustment knob f
always place the mains switch 8 at the position "O" (Off). This prevents
an accidental start of the appliance and thus the risk of injury!
• Open the front flap 0, this can make the adjustment easier to carry out.
• Turn the seam width adjustment knob f to the desired seam width
(Fig. 38). Orientate yourself on the scale on the stitch plate e
(Fig. 39).
Adjust sewing foot pressure
Upon delivery, the sewing foot pressure is set for medium-weight materials.
If you wish to use heavier or lighter materials, adjust the sewing foot pressure
as follows:
• For lighter fabrics, you need to reduce the pressure.
• For heavier fabrics, you need to increase the pressure.
Insert the small screwdriver into the hole on the upper side of the machine
(Fig. 40). The pressure adjustment screw is located here (A). Ensure that the
screwdriver slips into the slot of the pressure adjustment screw (B) (Fig. 41).
• Turn the screwdriver in the direction "+" if you want to increase the pressure.
• Turn the screwdriver in the direction "-" if you want to reduce the pressure.
Note:
To return to the factory-set default sewing foot pressure, turn the pressure
adjustment screw as far as it will go anti-clockwise (-). Then turn it 6 rotations in
a clockwise (+) direction.
The standard sewing foot pressure is reset.
