b.To increase the height of the suspension (raise the box):
To remove oil from the suspension circuit (where height is deemed too important for
example), it is necessary to go ahead as follows :
Attach the connector marked by a spot (the long green one) to the tractor.
Open the 2 external block valves (see photo).The middle valve should be closed
Set the relevant tractor distributor to "float" position until the required height is attained.
Reclose the 2 external valves and open the middle valve.
Release the residual pressure present in the pipe, whilst setting the tractor distributor to
"float".
Disconnect the (long green) tractor pipe.
Only the (short green) (vert court) drain return pipe should remain connected.
RECOMMENDATIONS FOR USE :
The tube which serves to regulate the height of the hopper must only be connected in
suspension interventions. In normal operations, this pipe must be attached tto the pipe box
door nose.
On the other hand, the "drain" pipe (oil return in the event of high excess pressure) must
remain permanenetly attached to the tractor.
AXLE OPTIONS BEFORE PRESSURE ABSORPTION (with 3 axles) :
A basic pipe (in a brown sheath like with the load transfer function) allows axle
command before absorption. In normal operating conditions (3-axle suspension), it is vital to
set the tractor distributor to "float".
This option is not recommended for 2-axle vehicles since it is incompatible with rear
steering axles. The combination of these two options would lead to vehicle instability.
