Can't lower strings

[FretsOnFire]

I'm trying to lower the string action on my Harley Benton mp4-eb but I'm having no luck at all.

 

I've set the neck etc but the string height just won't change. I've gone clockwise and counter clockwise and nothing. What am I doing wrong?

 

I've included a pic with the holes I've been winding

Counter clockwise should lower the saddles. Check that they aren't already bottomed out. Try and add a picture taken looking under the front of the saddles if you can...
