2

Detach the electric connection (4) of the pressure limiting solenoid valve (7)

After engine shutdown, compressed air continues flowing through some compressed air lines for approximately 3 min. Start working on the compressed air operating unit after this time.

3

Remove the compressed air inlet line (1)

Firstly, slacken the connection bolt (5) in two turns to release the pressure of the system and then remove it completely.
