Adjustment of modulating pressure with non-adjustable cap
D27.60-0017-01
1 Remove cap on vacuum unit.

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.

4 After adjusting, press the cap onto the vacuum unit.
