Using your Makita T - 01410 circular saw blade is easy. First, make sure your 6 - 1/2 - inch cordless circular saw has a 5/8 - inch arbor. Then, carefully install the saw blade onto the saw according to the saw's instruction manual. When you're ready to cut, hold the saw firmly and start the motor. Let the blade do the work, and guide it smoothly through the material for a fine cross - cut. As for maintenance, after each use, wipe the blade clean with a dry cloth to remove any sawdust or debris. Store it in a dry place to prevent rusting. If the blade becomes dull over time, it might be time to replace it. And always remember to wear safety goggles and other appropriate safety gear when using the saw blade.
