Using your Makita GT400M1D1 combo kit is easy. First, make sure your batteries are fully charged. The 2.5Ah battery takes 28 minutes or less, and the 4.0Ah battery takes just 45 minutes. You can check the charge level on the charger's digital display. When using the hammer driver - drill, choose the right speed setting based on your task. For light drilling, the lower speed might be enough, while for tougher jobs, switch to the higher speed. The impact driver also has 4 speed settings, so pick the one that suits your needs. When using the circular saw, always wear safety goggles. Make sure the material you're cutting is secured. The saw can cut through 2 - 5/8' at 90°, so plan your cuts accordingly. The flashlight is great for working in dark areas. It gives off 160 lumens and can last up to 55 hours on a single charge with the 4.0Ah battery. As for maintenance, keep the tools clean. Wipe them down after each use to remove dust and debris. Since the tools have XPT™ technology, they're resistant to dust and water, but it's still a good idea to avoid exposing them to extreme conditions. Only use genuine Makita® batteries and chargers to ensure the best performance and safety. Remember, there's a 3 - year limited warranty on the tool, battery, and charger, so if you run into any problems, you're covered.
