If the emergency opening procedure detailed above does not work due to
insufficient compressed air in the system or a mechanical blocking of the
door, then proceed as follows.

Door hydraulics (V-65 – 150 only)
The door hydraulics are found in the door hinge on the rear of the device
and ensure that the door closes smoothly.

Z3 Hydraulic cylinder
NR3 “Close door” throttle no-return valve
The door must be pushed against the hydraulic pressure to close it.
The flow through the hydraulics can be set using the throttle no-return
valve (NR3) on the hydraulic cylinder: The more the valve is opened, the
less resistance there is to the door being closed.
