Using the Nerf SurgeFire blaster is easy. First, assemble it as per the included instructions (no tools needed). Load the 15 darts into the rotating drum. You can choose to fire one dart at a time by simply pumping and pulling the trigger. Or, if you want to pour on the firepower, use the slam - fire mode. When using the blaster, always make sure not to aim at eyes or face. Only use the darts that are designed for this product and never modify the darts or the blaster. After use, store it in a dry place. If it gets dirty, you can use a soft cloth to clean it. Remember, this product has small parts, so it's not suitable for children under 3 years old.
