Using the Lupo KinetiCore helmet is straightforward. First, put the helmet on your head and use the Lazer TurnSys dial at the back to adjust it until it fits snugly. Make sure the brow vents are at the front for proper ventilation. When you wear sunglasses, place the arms in the recesses to avoid pressure on your head. To increase safety at night, attach the Universal Lazer LED at the rear using the Direct Mount. In winter, install the Winter Kit for extra warmth. Remember to always fasten the straps properly for a secure fit. As for maintenance, use a mild soap and water to clean the helmet regularly. Avoid using harsh chemicals as they may damage the helmet. Store the helmet in a cool, dry place when not in use. Check the helmet regularly for any signs of damage, and if you notice cracks or significant wear, it's time to replace it.
