Using the Teamsterz garbage truck is easy. First, make sure the 3 AAA batteries are properly installed. Then, press the 2 buttons on the truck to enjoy the 4 different sounds and see the realistic flashing lights. Your child can hold the truck and use the free - moving wheels to drive it around the city. The interactive garbage bin lever can be played with to add more fun. As for safety, keep the truck away from small children who might put parts in their mouths. Avoid exposing the truck to water or extreme temperatures. To maintain it, wipe it with a dry cloth regularly. If the sounds or lights seem to be getting weak, it might be time to change the batteries.
