How to get round bale string to wrap tight

NH648 4x5 round baler, the book doesn't go into much details about it....

 

The book says to snug the spring plate where the string passes through, but there is also a cone shaped spring loaded tip where the string feeds on the roll.. 

 

How is the best way to get tight strings on this baler, if the plate is snuged up the string doesn't like to start, if it's looser the string is loose also... Do I need to snug up the cone things the string passes through also..

 

How do I get tighter strings here.....
