After taking the cover off, and watching the lock operate while inputing the combination, I determined that the instructions I had were incorrect.
instead of:
"Left 4 times and stop at 80
Right 3 times and stop at 10
Left 2 times and stop at 60
Then turn right as far as it will go.
rotate door anti-clockwise to open."
the correct solution was:
"Left 4 times and stop at 80
Right 2 times and stop at 10
Left 1 times and stop at 60
Then turn right as far as it will go.
rotate door anti-clockwise to open."
while i had it apart i cleaned and re-greased the mechanisms. it needed it, there were a lot of steel shavings in it.
it's now operating better than before.
thank you again for all the help!
Here is the real situation with your safe combo as I have recreated it here to be sure this is what is really going on.
The drive cam is splined at RH installation which makes the actual drop in point 60.
Whoever changed the combination either on purpose or by mistake made your safe really a 2 number combination 4 turns left to 80 - 2 turns right to 10.
By setting the combination 4 turns left to 80 and then only 2 turns right to 10 makes all 3 wheels lined up and turning the dial left to 60 is the drop in point on the drive cam so all you have to do is turn it right the bolt pulls back.
So really both wheels 1 and 2 are set to 80 the 3rd wheel is set to 10 and the drive cam is being used as your 3rd number 60 which is way wrong to do but it works.
Hence you have a 2 number combination because the last number on the lock box being mounted in RH position with the drive cam being splined in the RH position the drop in number is always 60 no matter what the other numbers are it can't be any other way.
The safe really needs to have the combination reset properly. With the drive cam being splined in RH position the new last number in your combination cannot be 60 the last number to be safe should not be at least 10 numbers left or right of 60 which is the drop in point. This is the common rule is combination setting.
So example for proper working combo for a 3 wheel pack which you have could be:
4 turns left to 80
3 turns right to 10
2 turns left to 30
1 turn right to stop
Which the drop in point will always be 60 and dial will stop turning close to around 47.

I have proven this is the condition that is happening with your safe I have it recreated in front of me to check it.
