First of all, is there a drop zone? There is one point where rotating left comes a point of resistance and 10 numbers or so right of it there is a point of resistance when turning the dial right. Maybe (or probably) your lock doesn't have this. If it has choose a number opposite of this area. Otherwise take any one number.
Turn the dial five times or so in one direction to this number. Then change direction and turn to maybe 15 numbers before the chosen one. Then turn the dial quickly, but even over this number. You should then feel, that one wheel's pin comes into contact with another wheel's pin, by feeling the collision and/or by feeling an increase of resistance. Then turn the dial on until it is again roughly 15 numbers before the chosen one and repeat, repeat, repeat until you do not feel another wheel. Oh, and don't forget to count.

You can repeat this procedure to be sure.
