Caution: Danger of injury !

Adjust the throat plate only with the machine switched off.
Standard checking
The needle should penetrate the needle hole of the throat plate on one
side at the edge 1.
The throat plate has to be positioned as highly as possible.
Thus it is avoided that the material is pressed down too much at the
moment of the needle penetration.
During the sewing process there must be a small distance to the throat
plate at the following points:
·
Under the sewing material or the closed upper fabric clamps.
It must be possible for the sewing material to move over the throat
plate unhindered.
·
Under the lower fabric clamps.
·
Above the needle thread knife.
The needle thread knife must move as closely as possible under
the throat plate, but without touching it.
Correction
–
Adjust the height of the throat plate at the stop screw 2 in the throat
plate guide.
By means of the stop screw the adjustment is maintained when
inserting the throat plate anew.
