Caution: Danger of injury!

Adjust the guide plates only with the sewing unit switched off.
Standard checking
When the folder is lowered, the edges 3 of the guide plates 2 must
project from the needles by approx. 1 mm to the back.
The leaf springs 1 hold the guide plates down by a low pressure on the
folder sole.
The pressure must be set in such a way that the springy guide plates
can be easily lifted by the fed piping strip or by the flap. The height of
the guide plates over the soles has to be set in accordance with the
fabric.
