In case any voter, after entering the voting machine, shall ask for further instructions concerning the manner of voting, two of the managers shall give such instructions to him, but no manager or other election officer shall in any manner request or seek to persuade or induce any such voter to vote any particular ticket or for or against any particular candidate or for or against any particular amendment, question or proposition. After giving such instructions the managers shall, before the voter has voted, retire and such voter shall cast his ballot in secret.
