Install the door handle through the cutout in the door leaf. In this case, the seal on the door handle "1" must be placed behind the door leaf so that the protrusion engages with the locking bracket "2".
When installed correctly, the door handle projection "1" is caught behind the locking bracket "2". Insert the lock cylinder into the door handle mount.
Turn bolt "2" clockwise until it stops. This releases the locking device "arrow" of the locking bracket "1" and the door handle is pulled inward.
