Thats correct, lock up and run…..They have a sliding pin that changes from forward to backwards. Couldn’t be easier.You can get them in roman or gothic.What I like about the count is the No. can be removed. Count has slides from A to Z and a blank slide for numbering without anything for special numbering. If this is not to clear call me after September 20th. We are closed this week. 1-310-268-1466 ask for JoePS. be carefull of used machines.Joe
