i've got the older version, the f5, which is the coil sprung version. Not sure if yours is an air spring... mine says preload, rather than reload. the preload adjusts how difficult is is to compress the shocks. all the way out seems to be easier, and all the way screwed in is firmer.
I run mine all the way out. I weigh 125 pounds and ride the thing like a dh bike and have only been able to use about 75% of the travel.
