Using this truck is easy! First, if you want to change the container, just pull out the interchangeable unit and extend the outriggers to lift the container off the truck. You can then move the truck away. The forklift can be used to handle different parts of the disassembled container. When playing, make sure to keep small parts away from very young kids to avoid choking hazards. To keep the truck in good condition, wipe it with a soft cloth regularly. Avoid exposing it to extreme temperatures or rough play that could damage the mirrors, glazing, or other delicate parts. If you install the Light + Sound Module, follow the instructions that come with it for battery replacement and maintenance.
