Using the X - SHOT CRUSHER is a breeze. First, load the darts into the belt. You can use the single - shot function to aim precisely at opponents from a long distance. When the battle gets intense, switch to Slam - Fire mode for rapid - fire action. During Slam - Fire, you'll see darts shooting out quickly from the auto - rotating barrel. If you run out of darts, simply take off the belt, refill it with darts, and you're ready to go again. As for safety, this blaster is for ages 8 and up, so keep it out of reach of younger kids. For maintenance, store it in a dry place. Clean it gently with a soft cloth if it gets dirty. Don't try to modify the blaster, as it may affect its performance and safety.
