Using this toy is super easy. First, take it out of the box and check all the parts. You can start combining it with other compatible vehicles to form a robot. Just match the connecting points and snap them together. When using it with the DX VS Changer, follow the instructions on the changer to insert and operate the vehicle. As for maintenance, keep it away from water and extreme heat. If it gets dirty, use a dry cloth to wipe it gently. Don't try to force the parts together too hard to avoid breakage. Have fun playing with your new toy!
