Using this toilet paper dispenser is easy. First, open the dispenser by removing the tissue roll core to access the locking mechanism. Then, insert a single roll of toilet paper with a core of up to 6 inches. Close the dispenser, and you're good to go. When the paper runs out, repeat the process. For maintenance, clean the chrome - plated surface regularly with a soft cloth and a mild cleaner. Avoid using abrasive materials that could scratch the finish. Also, check the tension spring periodically to ensure it's functioning properly. If you encounter any issues with the locking mechanism, refer to the product manual or contact customer support.
