Using this Bradley toilet paper dispenser is a breeze. First, make sure to install it on a flat surface as it's a surface - mounted type. When it's time to refill, tear off the tissue core from the new roll and release the spring. Then, place the roll on the spindle. Remember, the spindle can only turn half a revolution, which helps control the paper delivery. As for maintenance, keep the dispenser clean by wiping it regularly with a soft, dry cloth. Since it has a vandal - resistant locking mechanism, it should stay secure in public areas. Avoid using abrasive cleaners as they might damage the aluminum finish. If you notice any issues with the locking mechanism or the spindle, it's best to contact a professional for repair.
