With the limbs off crank out your bolt counting the number of turns out so that you have a safe margin of bolt still in the riser or call Lan.... and ask them the max turns out. Then crank them in and back both bolts off either none, 1/2 or full depending on what you want your weight to be approx. Install limbs, set brace height with string turns. Using a bow square set the tiller by backing the top bolt off enough turns to give you 1/8" more than the measurement on the bottom limb measured where the limb meets the riser if you are shooting split finger. For 3 under most have them equal. Shoot the bow and make any adjustments you feel you need to make to get it shooting quiet.
I don't own a button but most suggest using the strongest spring and turn it out until you can see the arrow point on the left side of the string for a right hander. Then just bare shaft tune the arrow with the button adjusting it in and out to get good arrow flight.
