Using the Makita 5-Pack 6-3/8 #2 Phillips Power Bit is easy. First, make sure your Makita 18V LXT Autofeed Screwdriver (model XRF02) is turned off. Then insert the bit into the screwdriver until it fits securely. When using it for decking or subfloors, apply steady pressure and let the bit do its job. As for maintenance, after each use, wipe the bit clean with a dry cloth to remove any debris. Store it in a dry place to prevent rust. And always be careful when handling the bit to avoid any injuries.
