Using the ASI 0462-AD-9 is easy. First, open the tumbler - locked door to load the paper towels. You can use either 350 C - fold or 475 multi - fold towels. Just place them in the dispenser at the top of the unit. When you need a towel, simply pull it out from the hemmed opening. The waste receptacle at the bottom is for collecting used paper towels. When it's full, use the rolled finger hole to lift and empty it. As for maintenance, wipe the stainless - steel surface regularly with a soft cloth to keep it looking good. Check the hinge and lock periodically to ensure they work properly. Avoid using abrasive cleaners as they can damage the satin finish. Also, make sure to keep the unit away from excessive moisture to prevent rusting.
