➤ Do not convert or modify the machine!
➤ Obtain written approval by the manufacturer prior to any technical modification or expansion of
the machine, the controller, or the control programs.
Extending or modifying the compressed air system
If set appropriately, safety relief valves reliably prevent an impermissible rise in pressure. New dan‐
gers may arise if you modify or extend the compressed air network or system.
➤ When extending or modifying the compressed air system:
Check the blow-off capacity of safety relief valves on air receivers and compressed air lines
before installing a new machine.
➤ If the blow-off capacity is insufficient:
Install safety relief valves with larger blow-off capacity.
