We have a GE Definium 8000 radiology system. The tabletop (PN 5131070) moves flawlessly in three directions (head, away, and foot), but must be forcefully pulled to move towards the operator. Has another facility encountered this issue; if so, what actions were taken to restore movement (WD-40 DNA as no wheeled track exists). We lack a service manual for the table; does a related schematic exist for this table? The GE website - predictably - is of no use.
