Polo Sport Suitcase How To Reset The Combination For A Polo Sport 1000 Upright Suitcase?

How to reset the combination for a Polo Sport 1000 upright suitcase? - polo sport suitcase

I have a 1000 Polo Sport bag vertical, I bought at Costco. It came with a combination lock that a bit of cable and the three digits on the merits is set by default to 000. I opened it and tried to restore the other combination of numbers 3, but now will not close or block, even if in turn the number back to 000. Someone knows how to reset the lock? There is a button on the side, but do not go too far - what seems to be blocked.
