Using this Makita XT297T combo kit is easy. First, charge the 18V LXT® Lithium - Ion 5.0Ah batteries with the included charger. It takes about 45 minutes. Once charged, insert the battery into the tool you want to use. For the hammer drill, choose the right speed (0 - 550 or 0 - 2,100 RPM) based on your task. If you're drilling into masonry, the high BPM setting will make the job faster. When using the impact driver, select the appropriate speed from the 4 - speed power selections for precise fastening. The Assist Mode helps prevent issues like'screw cam - out' and 'cross threading'. Be careful when using the self - drilling screws with the Tightening Modes to avoid damaging the screw or workpiece. In terms of maintenance, keep the tools clean. After using them in dusty or wet conditions, wipe them down. The Extreme Protection Technology (XPT™) helps with dust and water resistance, but it's still a good idea to protect them. Also, don't overcharge the batteries. The Star Protection Computer Controls™ will help protect against overloading, over - discharging, and overheating, but it's best to follow normal charging practices. When not in use, store the tools in the provided tool bag in a dry place.
