Using this Maisto Tech RC Mack Granite Refuse Truck is a breeze. First, insert 4 AAA batteries into the vehicle and 2 AAA batteries into the pistol - style controller. Once the batteries are in, turn on both the truck and the controller. You can then use the controller to drive the truck around within its 115 - foot control range. It supports up to 4 players, so it's great for group play. When it comes to the manual rear hatch, you can operate it as you like during play. As for maintenance, keep the truck clean by gently wiping it with a soft cloth. Store it in a dry place when not in use. Remember to remove the batteries if you won't be using the truck for a long time to prevent battery leakage.
