b.To decrease the height of the suspension (lower the body) :
To remove the oil from the suspension system (for example, if the
height is considered too high), proceed as follows:
Connect the hose identified by a marking (long green) to the tractor.
Open the two outer taps of the block (see photo). The middle tap must be closed
Set the relevant distributor of the tractor on position "float" until the required
height is achieved.
Close the two outer taps again and open the middle tap.
Release the residual pressure present in the hose by positioning the tractor
distributor on "float".
Disconnect the hose (long green) from the tractor.
Only the return drain hose (green short) remains connected.
RECOMMENDATIONS FOR USE :
The hose used to adjust the height of the skip should be connected only in case of
need to work on the suspension. In normal operation, this hose should be stored on
the hose holder.
In contrast, the hose "drain" (oil reflux by high over pressures) must be permanently
connected to the tractor.
