Daily maintenance items
Before beginning work
In most cases, maintenance should be performed with the main power turned off.
However, some maintenance tasks are performed under emergency stop conditions with the power turned on.
In such cases, ensure adequate safety and press the emergency stop before beginning the maintenance.
The power is turned on during maintenance where any servo-axis must be operated or machine operation
checked. In this case, also ensure adequate safety before beginning the maintenance.
