to the elimination of this step later during emergency operation. This does
not affect the emergency operation of the other power units.
For crane operation
• Open the valve (4) and secure it using the
lock (2).
• Close the valve (5) and secure it using the
lock (1).
For emergency operation
• Take off the lock and close the valve (4).
