Conlan,

You adjust tiller by turning the limb bolts.

You can get real close to an even tiller by simply turning both limb bolts in and then backing them out an equal number of turns each.

You add tiller by tightening the limb bolts.

You subtract tiller by loosening the limb bolt.

I highly reccomend that you set your bow at an even tiller before you set your nocking point at the 90degree point on the bowstring.

If both limbs are pulling evenly (even tiller) then the bow should be capable of shooting the correct spine arrow in a level fashion from the 90degree position on the bowstring.

If the bow has had an additional turn on the lower limb bolt then it is going to push the arrow down into the rest when the bow is shot. If the downward force is sufficient enough to cause fletching contact with the windage bracket you have to adjust the bow tiller in order for the bow to shoot the arrow through the center of the biscuit.

Good luck tuning!

Good luck hunting!
