What should you do before performing maintenance on an elevator system?

Check for oil leaks
Inform your supervisor
Disconnect the power supply
Clean the work area

The correct answer is: Disconnect the power supply

Before performing maintenance on an elevator system, it is crucial to disconnect the power supply. This step is essential for ensuring the safety of the technician and preventing accidental activation of the elevator while maintenance is being carried out. By cutting off the power, you significantly reduce the risk of electric shock and create a safe working environment. Additionally, disconnecting the power prevents the elevator from moving during maintenance, which is critical for the safety of anyone who may be interacting with the system or nearby. This practice is a fundamental safety protocol that is consistently emphasized in the industry. Other options, while important in a broader maintenance context, do not directly address the immediate safety concerns associated with working on an elevator system.
