2 Pull adjusting key out of the locking cap until it can be rotated.

One clockwise rotation results in a pressure increase of 0.4 bar
One counterclockwise rotation results in a pressure reduction of 0.4 bar
To facilitate the work, the modulating pressure can be adjusted at idle speed when the vehicle is stationary

3 Adjustment process:
-Check and record modulating pressure at idle speed when the vehicle is stationary
-Check and record modulating pressure (at wide open throttle at 50 km/h)
-Compensate the calculated pressure difference when the vehicle is stationary (at idle speed).
- After the adjustment process, check the modulating pressure (at wide open throttle at 50 km/h) again and repeat the adjustment process if necessary.
