Using the Brave green concrete saw is easy. First, make sure you've chosen the right blade for your job. Attach the blade to the 5/8 - inch arbor as per the instructions. If you're cutting dry concrete, connect the vacuum nozzle to control dust. Adjust the handle height to a comfortable position for you. When you're ready to start, turn on the Honda GX200 engine. You can cut to a depth of 3.25 inches by rotating the handle for depth adjustment. You can saw right up to walls and columns for precise work. For safety, always wear proper protective gear like goggles and gloves. Keep your hands away from the blade while it's running. When not in use, store the saw in a dry place. Regularly check the engine oil level and change it as recommended by Honda. Also, inspect the blade for any signs of wear and replace it if needed.
