Lock on a udoor to adjust

Sometimes we have the following issue (cf image below) : due to the angle too low, the half-moon part does not rotate during doors closing. The result is the doors not closing completely
In this case you should use the adjustment screw to increase the angle
Be careful, if you increase it too much, then the gap becomes zero and the doors can't close for this other reason !

If you cannot even rotate manually the half-moon part because the latch is completely blocked, remove the latch (4 screws) and analyse it to understand the blocking
Cabin can work perfectly without the doors latches, their purpose being only to prevent the doors from reopening in case of bump with the trolley inside the cabin.
