8.4 Operation
Consult an expert when in doubt about the operation, safety or connection of
the device.
If it is no longer possible to operate the product safely, take it out of operation
and protect it from any accidental use. DO NOT attempt to repair the product
yourself. Safe operation can no longer be guaranteed if the product:
– is visibly damaged,
– is no longer working properly,
– has been stored for extended periods in poor ambient conditions or
– has been subjected to any serious transport-related stress.
