To use this Brio Lift & Load Warehouse Set, start by building the stackable bridges, curves, and sloping tracks up to the top of the warehouse according to your chosen layout. Place the wagon on the track and use the lift to carry it up. Then, unload the wagon and watch it roll down. When playing, make sure to keep small parts away from children under 3 to avoid choking hazards. To maintain the set, keep it clean and dry. If any parts get dirty, you can gently wipe them with a damp cloth. Store the set in a dry place when not in use to prevent damage.
