Using this Deltana spring hinge is easy. First, choose the right location on your door and frame to install the hinge. Make sure to use the provided #9 x 0.5 machine screws and #9 x 0.75 wood screws for a secure fit. You can adjust the tension of the hinge according to your door's weight and how you want it to close. Just turn the adjustment mechanism until you get the perfect closure. When it comes to maintenance, periodically check the screws to ensure they're tight. Wipe the hinge with a dry cloth to keep it clean. Avoid using harsh chemicals on the hinge as it may damage the finish. If you notice any unusual noises or difficulty in the door closing, check the tension adjustment again. With proper use and care, this hinge will serve you well for a long time.
