If an accident happens,

The operator must ensure that all maintenance, inspection and assembly
works are only carried out by authorized and qualified technical personnel.
Generally, only work at the system when it has been switched off and after
having it disconnected from the mains supply. It is indispensable to comply
with the procedure for stopping the stud welding system described in the
operating instructions (chapter 3.13).
Immediately after having completed your work, re-install and activate all safety
and protective devices.
The system may only be retrofitted and modified after consultation with the
manufacturer. Original spare parts and accessories authorized by the manufac-
turer guarantee safety. The use of other parts may result in the cancellation of
warranty for any consequences thus caused.
Working safety of the stud welding system supplied can only be guaranteed if
the stud welder is used in accordance with its purpose. The limit values indi-
cated in the chapter "Technical data" must never be exceeded.
