Using the Makita ML102 is a breeze. To switch between lantern and flashlight modes, just turn the selector knob. This will change the direction of the internal L.E.D. For outdoor adventures, you can use the hanging hooks on the top and bottom for hands - free lighting. When it comes to charging, use only genuine Makita chargers and charge the 12V max Lithium - Ion battery for about 60 minutes. The battery and charger are sold separately. Remember, this flashlight can run up to 9 hours at maximum. To keep it in good condition, since it has an enhanced dust and drip - proof design, it can withstand some outdoor elements. But avoid submerging it in water. After use, store it in a dry place. Also, always use genuine Makita batteries to ensure optimal performance and take advantage of the 3 - year warranty.
