Align the spring strut and the spring strut support bearing with each other

CAUTION: Laser beam.
Injury hazard!

Do not look into the laser beam.

NOTE: Laser class 2 according to standard EN60825-1 (1994) P ≤ 1 mW

NOTE: Schematic diagram is for example purposes. Some parts may differ in certain details.

During the installation, it is absolutely necessary to align the installation position of the spring strut with the installation position of the spring strut support bearing with the special tools 2 210 778 and 2 450 246.
This ensures a defined pre-tension at the screw connection of the spring strut fork at the bottom wishbone.

Position spring strut holder (1) on spring strut (3).
Push spring strut holder (1) onto spring strut (3) to stop in arrow direction and align with color coding.
When replacing the spring strut, attach a color coding.

Mount the laser (1) with the securing tool on the spring strut holder from the top.
Place the mirror (2) vertical onto the spring strut!
It is absolutely necessary to set the mirror (2) onto a clean level surface!
Do not position the mirror (2) on labels or spot-welds!

The laser beam must face the mirror.
Adjust the laser (1) with the adjustment screw (3) to project the laser beam via the mirror (2) to the mark (4).
Remove the mirror (2).
