From what i see from the picture the change wheels are all set to 50, this is a generac combo that any lock smith would try before drilling. most locks come preset from the factory set to 50. in order to run the combo you should turn left to 50, then back right to stop point.
look closely to each wheel the lines that represent each number, the bottom of the line is jagged, (gearing) the part thats inside that is also geared. The center part of the wheel pops out, the dash on the center part points to the combo number. Pop each part out and pop it back in when its lined up with the number you want the combo set to. avoid numbers between 85-15 above 85 and below 15
Now assemble the lock in the exact order that it was disassembled, dont mix fly wheels, spacers or wheels.
NEVER NEVER NEVER NEVER lubricate a lock. BRASS IS A SELF LUBRICATING METAL! oil, wd-40, ……. will cause wheels to walk, flys to stick. and is a giant no no.
I use rubbing alcohol to clean my locks, it evaporates quickly removes old goo, and oils. Leaves nothing but bare brass on bare brass. I also had a old timer tell me once in a pinch use zippo lighter fluid. if you oiled the lock take it back apart and re clean it.
also when changing the combo, or after taking it apart test the lock BEFORE closing the door. the lock will function the same if the door is open or closed. With the door open throw bolts out spin off combo, test a few times. before closing.
east to run combos are low high low. 20-75-20 or 15-80-25
