Using your paper towel dispenser is a breeze. Just unlock the door with the tumbler lock, open it up, and load your C - fold or multifold towels into the dispenser. Then close the door. When someone needs a towel, they can simply pull one out manually. As for maintenance, keep the dispenser clean by wiping it down with a soft, damp cloth regularly. Check the lock and hinge occasionally to make sure they're working properly. Also, when refilling, make sure the towels are loaded correctly to avoid jams. This dispenser is ADA compliant, so make sure it's installed in an accessible location for everyone to use easily.
