How to use: Put on the helmet by placing it on your head and adjust the chin strap using the steel D - ring buckle until it fits snugly. Make sure the helmet covers your forehead properly. Attention: Do not use the helmet if it has visible damage. Always check the helmet for cracks or other signs of wear before each ride. Avoid exposing the helmet to extreme heat or chemicals as it may damage the shell and liner. Maintenance: Clean the washable antibacterial liner, cheek pads, and chin strap covers regularly with mild soap and water. Keep the helmet in a cool, dry place when not in use. If you have an inflatable emergency release system, follow the manufacturer's instructions for maintenance and replacement.
