This is the one, right?
Well, as long as you got it in a package, let it stay on the bow.
I see you can adjust it in 3 different springtensions, so try to find the one that fits your arrows. A little more stiffer is better the loose set-up.
Make sure you put all the screws tight and dont try to adjust them to much.
I sugest you put shrinking tube over the prongs to avoid sounds.

Its not really a bad arrow rest.
What kind of new bow did you buy?
Let us know.
