When machines are undergoing repairs or adjustments, turning them off or unplugging them is crucial for safety. This action eliminates any risk of accidental activation, which could lead to severe injuries to the technician or damage to the equipment. It ensures that no electrical current is flowing, minimizing the chances of electric shock, burns, or mechanical accidents caused by unexpected movements or operations.

In addition, while checking for safety, maintaining equipment, and ensuring that adjustments are needed are all important steps in machine maintenance, they should only be performed once the machine is confirmed to be in a safe state—meaning it must be turned off or unplugged first. Thus, focusing on safety by ensuring that machines are powered down is the best practice during repair or adjustment procedures.
