They do not have conventional wheels like most combo padlocks. A pointer goes through a maze as you dial and if you dial it right, the last stop pulls back the latch. It is kind of hard to explain, but it is a tough lock to manipulate!!!
All 3 had similar dialing patterns but 2 of these were odd balls from all the others in my collection. On all my others, you can freely turn the dial around either direction as much as you want and it will not stop. On 2 of these, you can turn it right and come to a dead stop then turn left 1 & ¾ times around and come to another dead stop…….I thought they were broken at first but I thought it odd that they both stopped in the same exact spots so I didn’t give up.
As for dialing, all of my locks of this type, dial pretty much the same way: turn left to “0” and continue left to the first number counting the clicks (never mind the numbers on the face of the lock…..these work on clicks). After you stop on the first number, turn right counting the clicks to the next number, then left to the next, and then right to the last number and you will feel the latch pull back freeing the shackle. BTW, all of mine are 4 number locks.
I may do a short video on these locks when I have more time, so you can see them get dialed open. If I do that, I will post a link here.
