1 Separate the spreader parts from the sprues. The points of separation may need cleaning up with a knife or fine sandpaper.
 2 Insert the two gears into the main body of the trolley.
3 Push the two caps into the two holes between the gears. There may be some powder in the holes that needs to be cleaned out with a thin wire or brush.

4 Place the trolley onto the runners that run along the inside of the horizontal reach.

5 Insert the legs into the underside of the trolley, making sure the feet point outward. The holes in the trolley may contain powder that will need cleaning out before inserting the legs.
