Using the Makita BL1840BSCX3 starter pack is easy. First, charge the 18V LXT 4.0Ah batteries using the included charger. The charger has a built - in fan to cool the battery and speed up the charging process, which takes about 90 minutes. You can use the L.E.D. charge level indicator on the battery to check its charge status. When using the 18V LXT Brushless Angle Grinder, make sure to install the X - LOCK 5' Continuous Rim Diamond Blade properly. The X - LOCK system allows for quick blade changes. For hard materials like ceramic, granite, porcelain, tile, and stone, this blade will give you a smooth and fast cut. The cordless heat gun is handy for various heating tasks. Just insert a charged battery and you're good to go. When it comes to maintenance, keep the batteries in a cool, dry place. Avoid overcharging, over - discharging, or overheating them, as the STAR Protection Computer Controls are there to protect against these issues, but it's still good practice. Also, clean the tools regularly, especially the grinder after each use, to keep it in top - notch condition. Remember, this product comes with a 3 - year limited warranty, so if you have any problems, you're covered.
