Replace GU tilt and turn fitting

First of all, it is important that the gu turn-tilt fitting is in a vertical position. Otherwise the lever cannot be disassembled. The cap must then be removed by loosening the cap on both sides. This allows the cap to be pushed up. The screws are now visible. Place the handle in a horizontal position and remove the old gu turn-tilt fitting. The new handle can also be placed back in the horizontal position.
