Notes on compressed air connection systems

AH00.18-N-0001-01A


After engine shutdown, compressed air continues flowing through some compressed air lines for approximately 3 minutes.
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.
