(b)(4).(b)(6).The actual device was returned for evaluation.Reliability engineering evaluated the device and the reported condition was confirmed.An assessment was performed on the device which found that there was a cut in the cord, and the device ran and the cutter rotated in the load (safe) position (power broken).During repair it was observed that the castellations on the pawl release and lock cylinder were worn down.It was determined that the cut/hole in cord is due to mishandling of the device by allowing the cord to come in contact with a sharp object which punctured the cord or exerting extreme force on the cord during cleaning or use.It was further determined that the device being power broken was caused by worn castellations on the pawl release and lock cylinder.The worn pawl release and lock cylinder castellations are caused by trying to operate the device in the load position or by pushing down on the disconnect sleeve while the device is in operation.The assignable root cause was determined to be due to component damage caused by user error.If additional information should become available, a supplemental medwatch report will be submitted accordingly.
