The device was manufactured during 10/2002 and has been in the field for 12 years.The articulated arm of the 765dc was returned to the manufacturer for eval on 12/04/2014.Eval of the returned part was completed and the root cause of the failure was determined to be component wear, especially the two rotation stops above the horizontal arm being bent and partially sheared.The failure was found not to be the result of a manufacturing error.The 765dc installation/maintenance manual (g0112-99i) indicates that annual maintenance of the articulated arm is required to ensure proper operation.Additionally, the 765dc user manual (g0112-99u) indicates that a maintenance program must be established and recommends maintenance to be performed annually.No maintenance records could be located for this device.This concludes our investigation.
