Manually tilt the gantry after a tilt-drive malfunction (emergency)
Use this when the powered gantry tilt has failed and you must move the gantry to a safe or serviceable angle by hand — for example to free a patient, level the frame, or gain access. You drive the tilt mechanically by turning the power-cylinder motor output shaft nut with a socket wrench; the cylinder extends or retracts and the gantry tilts.

Safety
Hazard: Moving gantry with no motor control
Consequence: Crush / pinch injury to a person or damage to the couch when the tilt frame swings under manual drive
Avoidance: Clear the bore and tilt path of people and the couch top before turning the nut; turn slowly and watch the frame
Hazard: Live rotor / high-voltage slip ring and stored energy inside the gantry
Consequence: Electric shock while working behind the covers
Avoidance: Turn OFF the gantry breakers on the distribution board before removing covers and reaching into the base
Hazard: Over-travel of the power cylinder
Consequence: Mechanical stop damage to the tilt drive
Avoidance: Stop turning the nut at the mechanical tilt limits; do not force past the end stops
