Chronology :

The first report of an issue was February 18, 2022. A machine with approximately 6 weeks of use had the lower boom cylinder disconnect from the turntable causing the booms and operator in the platform to fall. There were no reported injuries but the machine was damaged. An inspection of the machine was conducted and the investigation into the root cause began. On March 25, 2022 a second report was received of the lower boom cylinder disconnecting from the turntable causing the booms and operator in the platform to fall. There were reported injuries and damage to the machine. The initial investigation of both machines indicated a lack of lubricant for the lower boom cylinder spherical bearing and retainment pin. The decision to recall was made on 3/29/2022. The time range of 1.5 years was chosen to include units that may be at Dealers and Installers that have yet to be put into service. Owners are required to lubricate the machine every 6 months after it is put into service. The two reported failures occurred within 6 months of the machine being put into service.
