According to the scaffolding layout plan, position the adjustable base jacks at designated locations to serve as the foundational support points for the entire frame.
Starter Vertical Post
Insert the shorter end (approx. 350mm) of the starter vertical post into the base jack, ensuring the bottom is level and fully seated in the recess to form a stable initial vertical post.
First-Level Ledger
Insert both ends of the ledger into the minor holes of the disc, pressing it flush against the outer wall of the vertical post, then secure it with wedge pins to complete the first horizontal connection.
First-Level Vertical Post
According to the scaffolding layout plan, continue inserting standard uprights onto the starter vertical post, progressively building the vertical framework upward.
Second-Level Ledger
Fix the second-level ledgers in sequence following the same installation method as the first level, further reinforcing the frame structure.
Diagonal Brace
Install the diagonal braces sequentially in a diagonal orientation, inserting both ends into the major holes of the disc and securing with wedge pins to enhance overall stability.
