Sewing-foot stroke and speed are interdependent. Through the

potentiometer the control unit recognizes the set sewing-foot stroke

and limits the sewing speed. The values are predetermined by the

control unit.

The preset sewing-foot stroke can be switched on during free seam

sequences by actuating the knee lever 1 or the switch 5.

The function of the knee lever is set via the tilt switch 2 (rested or

pushed operation).

The sewing-foot stroke is actuated as long as the knee lever 1 is

being kept pushed (pushed operation) or until the knee lever is

actuated the next time (rested operation).
