# Does the MRCU controller need any maintenance ?

## It is recommended that the following items be inspected periodically after each operation of the robot. If any abnormality occurs, stop using the product and contact your nearest Oriental Motor sales office.

Inspection Items  
Check to see if the openings in the controller are clogged.  
Check to see if there is no dust adhering to the controller.  
Check to see if the connection part to the controller is loose.  
Check to see if there is any unusual smell or appearance to the controller.  
Note  
The controller uses semiconductor components. Since static electricity may damage semiconductor  
components, be extremely careful when handling it.
