Using the Makita 199249 - 8 Rip Fence Kit is a breeze. First, make sure you have a compatible Makita circular saw. Take out the rip fence (part no. 165153 - 3) and the screw (part no. 251887 - 5) from the package. Install the rip fence on your circular saw following the easy - to - understand steps. It's designed for quick setup, so you'll be ready to go in no time. When using it, place the material you want to rip against the fence to get a uniform width. Just start your saw and let the fence guide the cut. As for maintenance, keep it clean after each use. Wipe off any dust or debris. Since it's made of metal, it's pretty tough, but avoid exposing it to extreme moisture to prevent rust. And always store it in a dry place. Remember, this fence is only for use with select Makita circular saws, so don't try to use it with other saws.
