People with insufficient skills may suffer injuries!
If you carry out troubleshooting and repairs yourself, you may encounter certain risks
and hazards that may entail severe injuries.
Therefore:
Do not open the welder. Do not modify the welder. Do not try to carry out repairs
yourself.
For any and all troubleshooting measures not explicitly mentioned and / or
described in this manual, you should call service personnel and / or contact the
manufacturer.
Be sure to adhere strictly to the hierarchy of responsibilities defined in the table.
When you're in doubt: do contact service personnel / manufacturer.
If damage does occur: minimise, contain and avert consequential damage.
NOTE!
In the event that problems occur more frequently due to above-average workloads,
you must adapt the inspection and maintenance intervals accordingly.
