Using the AS3 aluminium fuel cap is easy. Just turn it a quarter - turn to fit it onto your bike's fuel tank. It's designed to work smoothly and quickly. When using it, make sure your hands are clean to avoid getting dirt into the fuel tank. As for maintenance, you can wipe it down with a soft cloth every once in a while to keep it looking good. If you notice any signs of damage or if it doesn't fit properly, contact the UK company for support. They offer a 12 - month warranty, so you're covered. Remember, this is a 1/4 turn quick - release style cap, not the threaded version, so don't try to use it like a threaded cap.
