Service intervals

Observe the following maintenance intervals and shorten if
necessary, if the filling times are extended by 20 % under
comparable conditions (gas supply pressure, volume of the
compressed gas container to be filled, ambient temperature).
Only allow maintenance measures to be carried out by
authorized expert personnel.
