Using the Makita XPS01Z plunge circular saw is easy. First, make sure you have two 18V LXT batteries installed (batteries not included). You can adjust the cutting speed using the variable speed control dial based on the material you're cutting. For a smooth start, use the soft - start feature. When cutting, if you want more precise cuts, consider using the optional guide rail system. For bevel cuts, set the angle using the bevel adjustment, and the positive stops at 22.5° and 45° will help you get accurate angles. The depth adjustment is simple with the large scale. Just set it to the desired cutting depth. When it's time to change the blade, use the on - board hex wrench. Make sure to lock the blade in position with the locking lever for easier installation. As for maintenance, after each use, clean the saw. Use the large rear dust port to connect a vacuum system to keep the dust away. Also, check the batteries regularly and store them properly. And remember, always wear appropriate safety gear like goggles and gloves when using this saw.
