Using your ULAC Soloist U - lock is easy. First, set your desired combination using the resettable mechanism. To lock, open the shackle and place it around the object you want to secure, then close it. To unlock, simply enter your pre - set combination. When setting a new combination, make sure to follow the instructions carefully to avoid getting locked out. Remember to keep your combination a secret. For maintenance, periodically clean the lock with a dry cloth to prevent dirt and debris from building up. Avoid exposing the lock to extreme temperatures or harsh chemicals as this may damage the steel and the lock mechanism. If you experience any issues with the lock, contact our customer service for assistance.
