Using the Makita D - 67038 circular saw blade is easy. First, make sure your cordless circular saw is turned off and unplugged (if applicable). Then, attach the 6 - 1/2 - inch blade to the saw with the 5/8 - inch arbor. This blade is great for fine finish ripping, cross - cutting, and miter cutting on wood. When using it, hold the saw firmly and start the cut slowly. Don't force the blade through the material, let it do the work at its own pace. As for maintenance, after each use, wipe the blade clean with a dry cloth to remove sawdust. Keep the blade in a dry place to prevent rusting. If you notice the cuts are getting rough or the blade is not performing well, it might be time to replace it. Also, always follow the safety instructions of your saw and wear appropriate safety gear like goggles and gloves.
