Using this shield is easy. First, make sure your helmet is clean. Then, carefully remove the old shield and align the new Arai GP - 6 Series shield with the helmet's grooves and snap it into place. When it comes to maintenance, clean the shield regularly with a mild soap and water solution. Avoid using abrasive materials that could scratch the iridium coating. Also, store the helmet in a cool, dry place when not in use to keep the shield in good condition. Be careful not to drop or mishandle the helmet as it may damage the shield.
