On Abloy padlocks, there is a small hole on the side of the lock, at the heel of the hasp. Once the hasp is opened, remove the small Allen screw from inside the hole. This unlocks the retaining ring around the plug. Using the notches and a coin, unscrew the retaining ring and the plug is now accessible. Be careful to lay out the discs and spacers in order, and don't flip them.
When reassembling, be careful not to over tighten the retaining ring, otherwise you will be clamping the discs and the plug will be tight.
There is already a thread on Abloy's which covers about 7 pages. I'm not going to direct you to it because I can't be bothered to go looking for it. That's something you'll have to do a search for.

If it ain't broke.....pull it down and see how it works anyway!
