Using this Bobrick toilet tissue dispenser is easy. First, open the tumbler lock with the provided key. Then, place two standard-core toilet tissue rolls inside the dispenser. Make sure the rolls fit properly and can rotate freely. Close the dispenser and lock it. This helps prevent theft. When it comes to maintenance, wipe the satin-finish stainless - steel surface regularly with a soft, damp cloth to keep it looking clean. Avoid using abrasive cleaners as they can damage the finish. Also, check the lock and the internal parts periodically to ensure they are in good working condition. If you notice any issues, contact a professional for repair.
