Turn the hex wrench counterclockwise to move the door out. Turn it clockwise to move the door in.
Step back after each adjustment. Look at the door gap. Make further adjustments as necessary to correct the gap.
Repeat the adjustments on each hinge until the gap is equal along all sides.

Turn the wrench clockwise to move the door up. Turn it counterclockwise to move the door down.
