Check hoses, pipes, and couplings every day and replace if necessary.
Before every commissioning, check all connections for leaks.
Additionally, the operator must regularly check the complete hoses for wear and
tear as well as for damage at intervals that he/she has set. Records of these checks
must be kept.

has been exceeded:
