Filling the air suspension system from
an external source
If it is not possible to fill the air suspension system
via the tire inflation connection 1 or the coupling
head 2 (see page 81), the system can be filled
directly via the test connection 5.
Filling the air suspension system via the test
connection 5 requires a minimum pressure of
8.5 bar.
Filling the air suspension system via the tire inflation
connection 1 or coupling head 2 requires a

on the left-hand side of the vehicle below the
implement carrier.

If the air suspension control system fails, the test
connections 3, 4 and 6 can be used to raise and
lower the chassis (minimum pressure 8.5 bar).
