ENVIRONMENT DESCRIPTION

Description:	Requirements:
All lifting platforms currently recommended by BMW	Wheel alignment pits
Pillar-type lifts with set-down device 2 plunger-type lifting platforms with set-down device Repair stands with set-down device
No particular requirements have to be met in respect of the location at which the BMW KDS is used. The measuring device can be installed over working pits or on lifting platforms.	One measuring area (approx. 4.5 m x 7.0 m). The rotating plates must be pinned to the platform

The support surfaces for the rotating and sliding plates may only display the following maximum height difference:

from left to right ± 0.5 mm
from front to back ± 1.0 mm
diagonally ± 1.0 mm.

NOTE: A difference in the height of the rotary plates of ± 2 mm from left to right results in a measuring error of 4.8° in the camber.
As a comparison: The camber tolerance on the E36 is ± 10'. The tire tread difference or varying tire pressure cause measuring errors of the same magnitude.
