NOTE: The "Roll Out 2000" system minimizes paint, ergonomic and health-endangering damage.
WARNING: Follow safety instructions. Refer to SAFETY INSTRUCTIONS FOR WORKING ON VEHICLES WITH AIRBAG SYSTEMS (M4 2021-2023)  for working on vehicles with airbag systems (risk of injury).

Attention! 

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

Attention! 

Always keep both suction cups dry and clean to ensure optimum adhesion on the windshield.

Suction cup may not be applied at the damaged point (crack in window glass).

Lubricate spool if lock rattling becomes too loud.

Always wear safety goggles and protective gloves for your own safety.

Mounting suction lifters on windshield or rear window:

Secure position of lifting jacks as shown (view from outside):

  1. Suction cup lifter with double spool
  2. Suction cup lifter with single spool (as deflecting point)
  3. Window
  4. Cutting wire
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.
