Push the blower pipe 22 with its long arm into the throttle nozzle.
The position of the air outlet can be varied by turning and pulling
out the blower pipe.
–
Cut the pneumatic line 23 leading to the pivoting cylinder 5 cm
underneath the arm outlet.
–
Insert the Y-piece.
–
Lay a new pneumatic line from the connection 24 on the scissors
block to the Y-piece.
–
Shut the throttle 21 by turning the throttle screw 25 clockwise.
–
Switch the machine on.
–
Skip to the service menu.
–
Select the menu item T3.1.1 outputs. Activate the output Y2 for the
swinging out of the scissors.
–
The throttle 21 of the needle cooler now receives compressed air.
Adjust the desired air-flow by opening the throttle screw 25.
–
Quit the service menu by actuating the ESC key.

Test the function of the scissors swinging out by sewing a test
seam.
Attention!
Do not open the throttle completely. If the air-flow on the needle
cooler gets too strong, it impairs the swinging out of the needle
thread scissors.
