In order to avoid damage to the air bellows during mainte-
nance work they should be checked for any accumulation of
waste or dirt and, if required, cleaned.
The following cleaning agents are approved for cleaning
the air bellows: soap suds, methanol, ethanol and iso-
propanol.
The maximum permissible operating pressure of the
system is 4.0 bar.
The optimum air pressure is achieved when the vehicle is
standing horizontally. The minimum air pressure must be high
enough to ensure that the air bellows cannot snap through.
When the vehicle is empty this pressure is approx. 0.5 bar
(please check individually); when the vehicle is loaded the va-
lue will be correspondingly higher, depending on the loading.
