You can try pulling up hard on the shackle while turning the dials to see if you find either a binding point or a point where the wheels goes slack. Experiment this way to see if you can find the combination. Other than that you can use a thin shim to locate the flat spots on the wheels. Insert the thin shim beside the wheels and turn them feeling for the flats. Once you locate the flats on all of the wheels you will have found your combination. You may have to transpose the numbers up to 9 digits but this can be easily done by turning all 4 wheels together and trying at each stop.
