Using your Bobrick B - 273 toilet paper dispenser is easy. First, unlock the concealed locking device and open the dispenser. Then, place a roll of toilet paper up to 6' (150mm) in diameter onto the plastic spindles. Close the dispenser and lock it again. When you need toilet paper, simply pull it from the dispenser, and the controlled delivery system will provide a proper amount. As for maintenance, regularly wipe the satin - finished cast aluminum body with a soft, dry cloth to keep it looking good. If the locking device seems stiff, you can use a little lubricant. Be careful not to use abrasive cleaners as they may damage the finish. Also, always use toilet paper within the specified size limit to ensure smooth operation.
