Using your Deltana 6 x 4 Right - Hand Hinge is easy. First, make sure the door or cabinet where you'll install it is clean and dry. Then, align the hinge with the pre - drilled holes and use the #12 x 1 - 1/4' wood screws to attach it. Tighten the screws firmly but don't overdo it to avoid damaging the hinge or the surface. When using the door or cabinet, don't put excessive force on the hinge. For maintenance, wipe it regularly with a soft, dry cloth to keep it looking good. If it gets dirty, you can use a mild soap and water solution, then dry it thoroughly. Avoid using abrasive cleaners as they can scratch the finish. If you notice any loose screws, tighten them promptly to ensure smooth operation.
