This might not help you, but it sorta works for me.

I have a Browning safe with a S&G lock. The last number in my (all?) combination is "0". The tumbler is sticky and does not fall by itself - I have to quickly rotate the dial 5-6 digits either side of 0 to get the tumbler to fall. To put it scientifically, wiggle the crap out of the dial over the last digit. Centrifugal force is your friend. I have been meaning to get this fixed for the last several years.

Forgive me my nonsense, as I also forgive the nonsense of those that think they talk sense.
