2

Loosen the connection bolt (4) from the compressed air inlet (1)

After shutting the engine down, the compressed air continues to flow through some compressed air lines for approximately 3 min. For this reason, start working on the compressed air control unit, after this time has elapsed.

Firstly, slacken the connection screw (4) in two turns to release the pressure of the system and then remove it completely.
