To use this VEX Robotics backhoe set, first, spread out all the over 200 pieces on a clean and flat surface. Read the instruction manual carefully to understand the building process. Start assembling the main body of the backhoe, then attach the moving parts like the arm and the bucket. When you're done building, you can play with your backhoe and make it perform tasks just like a real one. For safety, keep small parts away from younger kids who might swallow them. After each play session, put the set back in its box to avoid losing pieces. To maintain the set, wipe the pieces with a dry cloth every once in a while to keep them clean. This will ensure your backhoe stays in great condition for a long time.
