• Make sure that there are no loose parts in the Servomotor mounting.
• If you are using a Servomotor with an Oil Seal, make sure that the oil seal is not damaged.
Also make sure that oil has been applied.
• If you are performing trial operation on a Servomotor that has been stored for a long period of
time, make sure that all Servomotor inspection and maintenance procedures have been com-
pleted.
