Adjust the couch-top supporting rollers (height, level, and sway)
Adjust the height of the couch-top supporting rollers A and B to eliminate unwanted couch-top flexing, then level the couch top (longitudinally and transversely) and eliminate couch-top sway. Work through the sequence in order — each later step depends on the setting made in the one before it.

Safety
Hazard: Letting the couch top contact only one of the two supporting rollers A, or forcibly correcting lateral wobbling of the couch top by hand instead of adjusting the rollers (step 2)
Consequence: Excessive force applied to the couch, resulting in damage to the couch top or to the couch-top wobbling-prevention mechanism
Avoidance: Adjust supporting rollers A so the center of each roller properly contacts the back of the couch top; do not allow contact with only one roller and do not force lateral wobbling straight by hand
