Using the Makita XPS01Z plunge circular saw is a breeze. First, make sure you have two fully - charged 18V LXT batteries installed (batteries and charger sold separately). Then, adjust the speed according to the material you're cutting using the variable speed control dial. For a smooth start, use the soft - start feature. If you want to make precise cuts, consider using the optional guide rail system. When adjusting the bevel, use the positive stops at 22.5° and 45° for easy and accurate angles. Always wear appropriate safety gear like goggles and gloves. When it comes to maintenance, keep the saw clean. After each use, use a brush to remove dust from the motor and other parts. You can also connect the large rear dust port to a vacuum system to reduce dust buildup. Check the blade regularly for wear and replace it when necessary. Use the on - board hex wrench for quick blade changes. Store the saw in a dry place when not in use to prevent damage.
