A very nice, stable acting, pleasant, maybe a little heavy combination lock, where you can set the 4-digit combination itself. As so the observed one and other, sadly lacking a little instruction on how to change because works exactly. Generally, I would have so desired by the prescribing, they have betrayed the same gimmick, because 'Ah..war easy' yes helps further not particularly. I want to catch up here. If someone wants tüffteln themselves to the fun not to take to get it himself, should no more;)
So change the numbers: The default is 0000 1. Open the lock with 0000 2. Enter the new combination on the lock is open See 3. open lock in the opening and tilt this small temple 4. push, twist, test, done! :)
