IMPORTANT: Take care when handling sharp-edged tools and cutting wire (risk of damage to head airbag and window glass).

NOTE: Optimum cutting is guaranteed when the cutting wire is at an acute angle to the adhesive bead. There is a risk of the cutting wire breaking if the angle is too obtuse.
The suction cup lifter (2) is used as the deflection point to achieve the corresponding angle.
Depending on the window glass version and the effort applied during cutting, it may be necessary to change the deflection point during cutting.
The suction cups without a spool can even be used as the deflection point.
