I'm thinking the guy was wanting to know how to adjust the lockrings for spring preload?
If answer=yes then--you can buy the proper tool or most people use a punch or screwdriver and hammer to turn the lockrings. loosen the top lockring first then loosen to tighten the bottom ring. then retighten the top ring.
if you tell us what type of bike we can give more help. Read Rich's link. Lots of good info there but if it seems overwhelming let us know. maybe we can break it down.
