If one of the balancing valves malfunctions (fault not provided for in UNI EN
280:2015), there are 4 normally closed valves placed on each of the dangerous
movements of the cylinders of the chassis. These valves are fed (kept open) only
if the chassis is inclined in the two axes by an angle lower than 3°, or if the
platform is below the transport height.
The system that controls the power supply is separated from the main one and
connected to an angle sensor and dedicated limit switch.
These valves are blocked in the normally closed position by means of lead wire.
Proceed as described below to restore the machine to normal operating
conditions:
1.
Repair the damaged hydraulic hose and/or connections
2.
Fill and bleed the hydraulic circuit
3.
Manually perform the lateral and longitudinal levelling
