NOTE: TECHNICAL INFORMATION
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.
