5. Maintenance
In order to maintain the device, perform the prescribed function test daily or before starting work.
Remove the batteries from the device if it is to be idle for an extended period.
The vacuum hoses must be checked for leaks and damage on a monthly basis.
The batteries must be replaced if the function test fails or cannot be performed, or if the
alarm generator becomes quieter. Replacing the batteries does not mean that the function
test does not have to be performed.
The replacement interval depends on use conditions and the frequency of alarms.

It is recommended to replace the batteries of the warning device during the yearly accident prevention inspection
of the entire lifting unit.
Additionally, a complete lifting procedure with simulation of a leakage should be carried out during the yearly
accident prevention inspection.
