Key management
Safety covers on the machine are equipped with safety switches. In the event that either front or rear of the
safety cover is opened accidentally during automatic production, the machine will come to an emergency
stop to ensure the safety of the operators.
When you encounter a section in the manuals that reads [Turning OFF the power switch], a lock is needed.
The key for the lock should be managed by a trained person, according to the customer’s management
standard.
