DEVICE MANUAL RELEASE
Releasing the device may be dangerous for the user, if the boom fastening has been damaged or if the boom is no longer intact, as the result of an accident or
installation error.
In these cases, the tensioned springs no longer guarantee that the boom is balanced. The boom may suddenly rotate when being released.
Manual release may cause the operator to move in an uncontrolled manner due to a mechanical fault or an imbalance.
With the gearmotor released, the operator does not work.
The balance springs must not be tensioned (boom vertical) when performing maintenance on the barrier.
