Safety precautions to be observed during operation
Continued
WARNING
- Waterproof cover lock
When the machine power is ON and during spindle rotation, the
waterproof cover is locked. If the machine power turns OFF during
spindle rotation (by EMO switch activation, power failure, etc.), the
waterproof cover is locked and does not open even when the
machine is OFF.
If it is necessary to open the waterproof cover while power cannot
be restored, the cover lock cylinder has to be released. Performing
maintenance with the cover lock released may cause injury to the
personnel or damage to the machine. Maintenance tasks must be
carefully performed by the qualified personnel. While a maintenance
task is being performed, no one must touch the machine except the
maintenance personnel (for detailed interlock operation
descriptions, see section 7 of this chapter, [Interlock Mechanism]).
- Circuit breaker lever lockout
Before performing maintenance tasks with the machine turned OFF,
lock up the circuit breaker lever with a padlock or the like. Observe
this precaution to prevent irrelevant persons from inadvertently
touching the machine to invoke unexpected operations. For circuit
breaker lever lockout, perform the following steps:
1) Turn OFF the key switch, which is located at the right of the
monitor, and then take out the key.
2) Turn OFF the circuit breaker lever at the rear side of the
machine. As shown below, lock up the circuit breaker lever with a
padlock or the like.
