Assembly Instructions
Step 1: Assemble the Base
Take the five base support pieces and connect them to the central base hub. Ensure they are securely fitted.

Step 2: Attach Gas Lift Cylinder to Base
Place the central base assembly on a flat surface, preferably a rug to prevent scratching. Insert the gas lift cylinder into the central hub. Secure the base arms to the central hub using ten (10x) screws (part 122898/149697) and ten (10x) washers (part 100842). Use Allen key (part 124345) for tightening.
