What must be done to a motor before service?

Before servicing a motor, it is critical to ensure it is safely disconnected from the power source and properly locked out. This procedure is essential to protect the technician from electrical shock or accidental startup while performing maintenance. Lockout/tagout procedures are standard safety protocols designed to ensure that machines are completely shut down and unable to be started up again until maintenance or servicing is completed.

Properly locking out the equipment includes turning off the power, disconnecting power sources, and using a lock or tag to indicate that the circuit must not be energized. This step helps to create a safe working environment so that the technician can perform their tasks without the risk of electrical hazards.

While testing for voltage or applying oil may be necessary during the servicing of a motor, these actions should only occur after the motor has been securely locked out to ensure the technician's safety. Rebooting the motor is not relevant during maintenance processes, and it does not contribute to safety practices. Therefore, disconnecting the motor from the power source and properly locking it out is the most crucial initial step before any service work can be performed.
