Using this miter base is easy. First, mount your Blue Ripper G2 or Jr Rail Saw to the base with the four bolts and two pins provided. Then, you're ready to make 45 - degree miter cuts. If you want to do straight cuts, just remove the saw from the base quickly. Remember, this base won't work with Blue Ripper G2s made before August 2019 and Blue Ripper Jrs made before November 2019. If you're not sure if it's compatible with your saw, give our sales team a call at 800 - 342 - 3876. After use, keep the base clean and dry to maintain its performance. The saw and rails need to be bought separately, so plan your purchase accordingly.
