② Insert the center link through the top hole and into the main gear bolt.

③ After fixing the center link with the rubber ring, check the operation by turning the auxiliary gear in the direction of the arrow.

④ Insert a short bolt in the middle of the finished horse. Then insert it into the center link hole and fix it with a rubber ring.

⑤ Rubber ring is fixed to the center link.

⑥ The links of the hind legs and head are moved to the front, and the links of the front legs are moved to the rear, and fastened with long bolts.

* The front part overlaps and fixes two links.

⑦  Fix the bolt with rubber ring on the back side.

⑧ Completed look.
