Using this U-lock is easy. Just place the shackle around the part of your bike you want to secure and the fixed object, then insert the key and turn it to lock. Remember to keep the key in a safe place. When it comes to maintenance, you can clean it with a damp cloth regularly to keep it looking good. Avoid using harsh chemicals as they may damage the lock's finish. Also, try not to expose it to extreme temperatures for a long time as this could affect its performance. With proper use and care, this U-lock will serve you well for a long time.
