Using this sanitary napkin and tampon dispenser is easy. Just insert 25 cents into the coin mechanism if you're using the paid option, or if you have the free - operation Model 4017, no coins are needed. Then, open the door using the provided key and take the napkin or tampon you need. When it comes to maintenance, regularly check the coin box and empty it to avoid jams. Clean the dispenser with a mild soap and a soft cloth to keep the satin finish looking great. Make sure to refill the dispenser with napkins and tampons when the stock is low. Always keep the replacement keys in a safe place. And if you need to change the mounting style, you can use the appropriate replacement collars.
