occupational and accident prevention practices and in accordance with the requirements of
the ATEX- directive for machines and protective systems for the designated use in explosive
environments, as well as the requirements of the Machine and Product Safety Act [GPSG or
equivalent other national regulations]. They correspond to the state of the art.

inappropriate use or

.
For this reason, all instructions for the use of the blower must be adhered to.
