Using the Bobrick B - 9262 Fino paper towel dispenser is easy. First, unlock the unit with the provided key. Then, swing the cabinet down. Load your C - fold or multifold paper towels onto the TowelMate inside the cabinet. Pull one sheet of the paper towel over the TowelMate towel rod and out. This will conceal the rod and start the dispensing process. The slots on the sides of the cabinet will let you know when it's time to refill. When installing, use four #10 x 1 - 1/4' sheet - metal mounting screws (not included) at the points marked with an 'S'. For plaster or drywall, add concealed backing according to local building codes. For other wall surfaces, you can use fiber plugs, expansion shields, 1/8' (3mm) toggle bolts, or expansion bolts. As for maintenance, keep the dispenser clean with a mild cleaner. Avoid using abrasive materials that could scratch the stainless - steel finish. If any part shows signs of damage, refer to the 5 - year limited warranty for repair or replacement options.
