    It's quite confusing, you have a SM74 from 1980s??? As far as I know SM74 came to the market in 1994. It should be SM72. What is your problem? Are you talking about mechanical counter?

    Ok, try to find the switch under Feeder table, left hand side. It's running over a small cam. You can adjust or necessarily change it.
