Start at the number zero
- from zero 3 complete turns to the right to zero and then to the 1st number, e.g. 30
- from 30 1 complete turn to the left to the 1st number (30) and then to the 2nd number, e.g. (18)
- from the 2nd number (18) turn right directly to the 3rd number (ex. 3) and then pull the bar.

thank you very much, top!
