8.2.2 Emergency override
WARNING
Risk of injury in event of inadequate qualication
Improper operation of the emergency override can result in severe injury and damage to property.
►
The emergency override may only be operated by trained personnel or instructed persons.
►
After the emergency override has been operated, the locking, opening and holding function, as well
as the drift, must be checked as per the functional check procedure.
Maintenance intervals
Inspection interval specied by ride manufacturer.
It must be ensured that any damage to the pressure tube and actuating button which leads to a
functional failure of the emergency release is reliably detected. The area around the button must always
be kept clean to prevent dirt from entering the valve. The emergency override valve is better protected
against environmental effects when tted with a rubber cap, and cleaning it is then also much easier.
