11.2 Removing the door
Open the door completely and insert the pins (supplied) into the holes
from the inside. Close the door to an angle of about 45° and lift it off. To
reassemble, fit the hinges into their grooves, then lower the door into place
and extract the pins. If you should lose the pins, two screwdrivers can also
be used.
