Using these pad centering devices is a breeze. First, make sure your scrubber or buffer pad driver is clean and ready. Then, simply attach the device to the pad driver. It can work on machines with either left or right rotation, so no need to worry about the rotation direction. For best results, it's recommended to use them on high - speed machines. When it comes to maintenance, since the spring is made of stainless steel, there's no need to worry about rust. Just keep the device clean after each use. If you notice any issues, check the attachment points to make sure they are secure.
