Using this Deltana hinge is easy. First, find the right position on the door and the door frame. Then, use the provided #12 x 1/2' machine screws and #12 x 1 - 1/4' wood screws to install the hinge firmly. Make sure the hinge is properly aligned for smooth operation. When using the door, avoid slamming it too hard as this can put extra stress on the hinge. For maintenance, clean the hinge regularly with a dry cloth to remove dust and debris. If the hinge starts to make noise, you can apply a small amount of lubricant to the ball bearings. Keep the hinge away from excessive moisture to prevent rusting. This will help ensure the hinge lasts a long time and continues to function smoothly.
