14. Maintenance intervals
14.1. Usage-related maintenance
The described maintenances become necessary through the demands of the system operations. The
maintenance intervals are recommendations. Depending on the application (multi-shift operation, dust
generation, ...) it may make sense for the operator to change the intervals of maintenance, replacing
and cleaning. However, at the latest when the signal horn sounds, filter elements must be changed.
Maintenance work must always be documented by means of a protocol.
The approach of the maintenance measures is described in chapter "Maintenance".

14.2. General maintenance
The described maintenances are independent from the demands of the system operations.
The operator is obliged to carry out repeated inspections and functional tests according to national
regulations. If not otherwise covered by national regulations, the described maintenance intervals must
be respected.
Maintenance work must always be documented by means of a protocol.
