Adjustments to the Blow Tube (Supporting Air)
For optimal support during the acquisition of the label of the applicator the supporting air is to be set up so that it is
free of turbulence and evenly pushes the label against the pad.
The default air pressure value is set to 2 bar.

Note!
When changing the used printer type (2", 4" or 6") the respective blow tube is to be used. With the correct
blow tube the quantity of blow holes used and the air pressure and blow tube allignment should be adjusted
respectivly.

Adjustment to the blow tube
The blow tube (3) for the relative air pressure can be turned on its own axis to optimize the support for the label
acquisition.
1. Loosen screw (1).
2. Insert the blow tube (1) into the blow tube-slot B (2).
Turn the blow tube so that the airflow supports the label from the dispencing plate (5) to the pad (4).
•
For smaller labels turn the holes of the blow tube into the direction of the dispencing plate (4).
•
For larger labels guide a stronger airflow away from the dispencing plate (5) toward the pad (4).
Better orientation can be obtained by using the indicator at the base of the blow tube.
3. Tighten screw (1).

Throttle valve for supporting air
The force of the compressed air can be varied via the throttle valve (1) to improve the blowing onto the label.
To strengthen the supporting air turn the throttle valve (1) counter-clockwise.
