Safety

ARROW DAMAGE OR BREAKAGE
Any arrow can become damaged. A damaged arrow could break upon release and injure you or a bystander. Damage to an arrow shaft, or any of its components, may occur from: improper transport, handling, or use; impacts with hard objects or other arrows. No list can cover all possible conditions and situations that may cause damage. Use good judgment and common sense, as well as follow the warnings and instructions below, to determine if your arrow has been damaged in any way.
WARNING! NEVER SHOOT A DAMAGED ARROW.

ARROW USE PRECAUTIONS
Before each shot (including the first shot of a new arrow) carefully inspect each arrow shaft, nock, and other components to see that they have not been damaged. Before shooting, place the arrow between your thumb and fingers, and using your other hand to slowly rotate the shaft, run your fingertips along the entire arrow length, feeling and looking closely for nicks, cracks, splits, dents, or other marks that could indicate the shaft has been damaged. If shaft damage is present, DISCARD THE ARROW. WARNING! NEVER SHOOT A DAMAGED ARROW. Before each shot, inspect the nock for damage. If the nock is damaged, replace the nock. WARNING! NEVER SHOOT AN ARROW WITH A DAMAGED NOCK. Before each shot, check that the nock is fully seated, and fits tightly onto the string. Apply twisting pressure to see if the nock turns easily. If the nock has backed out of the arrow or the fit is loose (rotates easily), inspect further for cracks in the nock end of the arrow shaft. If there are cracks in the shaft or the nock is loose, DISCARD THE ARROW. WARNING! NEVER SHOOT A DAMAGED ARROW.
