A steris service technician arrived onsite following the reported event to inspect the 4085 surgical table and found that the table was leaking hydraulic oil and the leg section would not operate correctly.The technician found that a banjo bolt within the surgical table had broken in half.The banjo bolt connects the hydraulic oil hose to the table's leg cylinder and allows the oil to flow between the two parts.When the bolt broke it caused the oil to leak out and the reported event to occur.Upon further inspection, the technician found the root cause of the reported event to be attributed to the set screw that holds the leg cylinder in place.The set screw was loose which caused the leg cylinder to move out of position.This allowed excess pressure to be placed on the banjo bolt causing it to break.The technician replaced the leg cylinder and banjo bolt, tightened the set screw, tested the surgical table and found it to be operating according to specification.No additional issues have been reported.
