When a machine error occurs, switch off the main power. If you need to keep the machine off, perform a lock out and tag out.
Lock out and tag out the machine to prevent a third party from operating it erroneously, preventing incorrect operation and maintaining a safe situation.
Lock out
Switch off the main power, and then lock the switch so it cannot move from the off position.
Tag out
Apply a tag to the machine to indicate that it is being inspected or cleaned.
When you are finished the work, remove the tag and unlock the switch.
