Using the Makita BL1840BSC2 starter pack is easy. First, charge the 18V LXT Lithium - Ion 4.0Ah batteries using the included DC18SD charger. It'll take about 90 minutes for a full charge. You can check the charge level with the L.E.D. indicator on the battery. Once charged, insert the battery into your 18V 'bare tool' or the included circular saw. Make sure the tool has the Star Symbol™ or a Yellow Battery Receiver to be compatible. When using the tools, don't overload them as the Star Protection Computer Controls™ will protect against this, but it's still best to use the tools as intended. Also, avoid over - discharging the batteries. If you notice the tool not working as well, it might be time to recharge. For maintenance, keep the batteries and charger in a dry place. The batteries resist self - discharge, but it's a good idea to charge them every few months if they're not in use. The impact - resistant outer case and shock - absorbing inner - liner of the battery are designed to protect it, but still handle it carefully. This starter pack comes with a 3 - year limited warranty, so if you have any issues, contact the manufacturer. And remember, you can use two 18V LXT batteries on 36V (18V X2) LXT tools for extra power.
