Using the Makita XDT19T is easy. First, charge the 18V LXT Lithium - Ion 5.0Ah batteries with the included charger. Then, insert a battery into the impact driver. To change the speed, just use the one - touch 4 - speed power selector button under the chuck. When driving screws, use the Assist Mode to prevent issues like 'screw cam - out' and 'cross threading'. If you're working with self - drilling screws in thick or thin metal, switch to the Tightening Modes for faster and safer tightening. When loosening fasteners, the reverse rotation auto - stop mode will help you avoid over - loosening. As for maintenance, keep the tool clean. After using it in a dusty or wet environment, wipe it down. The Extreme Protection Technology (XPT) helps resist dust and water, but it's still good to take care of it. Also, don't overcharge the batteries. Use the Star Protection feature to ensure the tool and battery stay in good condition. When not in use, store the tool in the included tool bag in a dry place.
