Using this Fisher-Price Thomas & Friends Diesels Lift & Load Construction Set is super easy. First, make sure you have 2 AA batteries (not included) and put them in the battery-powered Diesel engine. Then, connect the 5 feet of track. You can also connect it to other Thomas & Friends track (except wood) to make the railway bigger. Flip the switch on top of Diesel, and the train will start racing around the track. It will pick up barrels, which will automatically unload into the elevator. Lift the elevator to send the barrels rolling down the chute to the loader, and then Diesel and the Troublesome Truck can pick them up again. This is a great way to have fun and develop fine motor skills. Remember, this set is not suitable for children under 36 months because small parts may be generated. To keep the set in good condition, store it in a dry place when not in use. If the track gets dirty, you can gently wipe it with a clean, dry cloth.
