3.2 Disinfection
Masks should be disinfected after having been
cleaned as described above.
The disinfectant MSA AUER 90 or MSA Cleaner

Instructions for Use of disinfectant. After disinfec-
ting thoroughly, flush all components with water,
dry and reassemble (see table 5 for disinfection
intervals).
4 Maintenance
Maintenance of the full face mask must be per-
formed by the maintenance technician (if there is
none, by the user). It includes the visual check, the
functioning and leak tests, as well as replacing
components.
4.1 Visual and Function Test
The visual and function test serves to identify
damaged components and functional disorders,
especially at the valves and harness. In case of
doubt about the functioning of a component, it
must be replaced immediately or the MSA AUER
customer service must be contacted.
Part of the visual test is to ensure adherence to the
test intervals according to Sect. 5.
4.2 Leak Test
The leak test is performed with the MSA AUER
leak test kit; its operation is described in the kit's
Instruction Manual.
The MSA AUER Customer Service should be con-
sulted prior to using leak test kits of other manu-
facturers.
4.3 Replacement of Components
Only MSA AUER spare parts must be used for
repair. After the replacement of components a
complete test must be done.
