As with any arrow, the arrow must be inspected for damage before each shot. Use of the arrow can create damage due to impacts with animals, other arrows or objects. Damaged arrows can break during release causing injury to bystanders or the archer.
DO NOT SHOOT an arrow that you believe has been, or might be, damaged.
CUTTING ARROWS
Arrows should not be cut less than one to one and a half inches in front of the arrow rest. Cutting arrows too short can result in the arrow being lodged behind the riser of the bow or behind the arrow rest. SHOOTING A BOW IN THIS STATE WILL CREATE ARROW FAILURE, AND CAN CAUSE EQUIPMENT DAMAGE AND BODILY INJURY.
HUNTING WITH CARBON ARROWS
Carbon shafts used in hunting can break from impacting the animal, or from the animal's reaction (ie: falling on embedded arrow). Only until after recovery of the animal can it be determined if there is a break.
When a carbon arrow breaks, it can shatter into many splinter-like fragments. Fragments can be harmful to humans if ingested. This must be taken into consideration when hunting, and special precautions should be taken when doing so. ALWAYS carefully determine if there has been damage to the arrow when game is recovered.
INSTRUCTIONS FOR REMOVAL OF BROKEN CARBON ARROWS:

To ensure safety and true flight, MEGA THRUST ARCHERY RECOMMENDS:
1. Use ONLY 4-Vane Fletchings with arrow shafts that have 4 Slits.
Likewise, use ONLY 3-Vane Fletchings with arrow shafts that have 3 Slits. Simply trim a vane off to create 3-Vane Fletchings; do not force 2 vanes into one arrow shaft slit.
2. Mega Thrust® Archery recommends ONLY using approved Mega-Fletch™ Stabilizers with Mega Thrust® Slitted Carbon Arrow Shafts.
