2. Insufficient pressure in-
the pneumatic system.
3. The pressure reducing val-
ve is closed or wrongly ad-
justed (valid for the versions
that use this kind of device).
4. The tire is not com-
pletely deflated. 1. Connect the pneumaticsystem.
2. Adjust pneumatic pressu-
re to the correct value.
3. Open or adjust correctly-
the pressure reducingvalve.
4. Remove the valve ele-
ment from the valve until com-
plete deflation of the tire.
When operating the control lever of the 2 posi-
tions column, the correct movement of the co-
lumn (lifting/lowering) does not correspond. 1. The operating pipes of the
2 positions column are in-
correctly connected. 1. Invert the connection of the
operating pipes of the 2 posi-
tions column on the joints co-
ming from the control lever.
The manometer does not indicate the correct pres-
sure when operating the inflation pedal. 1. The connecting pipes
of the manometer are in-
correctly connected. 1. Invert the connection of the con-
