1

Remove compressed air line at compressed air inlet (1)

After turning off engine, individual lines are scavenged with compressed air for about 3 minutes. For this reason, do not start any work on the exhaust aftertreatment system before this time has passed.

First loosen union nut (4)
by about 2 turns to release the pressure, then remove it.

Remove compressed air line at compressed air outlet (2)

First loosen union nut (3)
by about 2 turns to release the pressure, then remove it.
