Arm installation instructions: The installation of the mechanism is straightforward. Simply place the special diagram on the door, using the hinges as a guide, and depending on the opening you want (120° or 180°), the points where the holes should be made will become apparent. Then proceed to install the arm with the part that screws to the frame in a nearly vertical position.

Mechanism adjustment instructions: With the screws on the side, it can be adjusted to close exactly how you want it with two speeds. The first speed takes time from the full opening of the door to about 20° remaining for quick closure, and vice versa. That is, quickly until 20° and then a brake until closure to avoid a loud bang against the frame.

Attention: Under no circumstances should you completely unscrew the screws, as the oil inside loses its pressure and cannot be adjusted again.
