Denali plow spring question.

I got my Denali plow put together and bolted on today to make sure it all fit and was ready to go. The only thing I didn’t see in the instructions is any recommendation on how tight to put the two springs on the plow? It has a long threaded bolt and two nuts for each spring so the tension could be adjusted. Is there a recommended amount of tension on the springs or should they be loose, and just tighten the nuts enough to keep the springs attached??
