can impair braking performance and may even
lead to failure of the entire pneumatic system.

4.5 Disconnecting and
reassembling
The pneumatic line connected
must be free of any pressure
before it is detached. If the
plug is detached while the line
is pressurised, it can cause
personal injury and damage to
connecting components or to
the pneumatic unit. These
damaged components must
then be replaced. All individual
components must be cleaned
before reassembly.
In order to replace compo-
nents, loosen the male nut
and remove the connection.
The nylon tube with plug and
coupling element with o-ring
need not to be separated.
Check the port on the new
unit is clean. Then re-grease
the thread-sealing o-ring,
screw in coupling element
with plug, fitted with nylon
tube and tighten male nut.
(For tightening torque, see
section 4.3).
Final assembly:
Inserting plug and subsequently pulling back to check
correct fitting
Final assembly:
Incomplete connection at first snap-in stage; the dirt-protection
and pretension o-ring is visible after pulling back the plug.
