How it works
Since the lock is activated via compressed air, a compressor or other source of compressed air is required. 
The compressor is activated by the driver via a dashboard button. The pressure in the expansion tank is monitored by a regulator and operates in the working range of 5.9 bar to 6.9 bar. When the locker button is pressed, the pneumatic valve opens and allows compressed air to reach the differential via an air line that connects them.
