Using your ULAC chain lock is a breeze. First, set your desired combination on the resettable lock mechanism. To secure your bike, wrap the chain around a fixed object and through your bike's frame, then lock it using your set combo. For storage, use the ULAC velcro to neatly bundle the chain. You can carry it by wrapping it around the top tube or seat post of your bike. When it comes to maintenance, keep the lock and chain dry to prevent rusting. If the chain gets dirty, you can clean it with a mild soap and water solution. Avoid using harsh chemicals as they may damage the nylon sleeve. Also, don't force the lock if it doesn't open easily; instead, double - check your combination.
