Using this kids' BBQ set is easy. First, make sure the battery is properly installed in the grill. Then, take out the included tongs and spatula. Your child can place the hotdogs, hamburgers, steak, kebabs, or corn on the grill. Watch as the grill lets out steam, just like a real BBQ. When your child is done playing, carefully remove the food items. As for maintenance, keep the set in a dry place. If it gets dirty, you can use a damp cloth to wipe it clean. Make sure to keep small parts away from younger children to avoid choking hazards. And always supervise your child while they're using the set.
