7.3 Snap ﬂange coupling, ﬂask seal and vapor duct

Removal / installation of the snap ﬂange coupling

Turn the snap ﬂange coupling until the unlock rocker at the left half of the snap ﬂange is in top

position.

Open both levers of the snap ﬂange.

Use the seal tool (order no. 20075) to unlock the metal reed and free the snap ﬂange.

Carefully pull off the snap ﬂange from the metal reed locking.

For reinstallation plug the coupling back onto the ﬂange. The metal reed snaps into locking position

with a noticable click sound.

➡ After installation, see also section 5.16 for correct adjustment of the lever tension!
