A bolt will not start by hand
Remove it. Confirm BLT-S is used for the feet and BLT-L for the upright, then realign the holes. Stop and use the support route if the correct bolt still catches or the thread looks damaged.
Complete assembly instructions for one fictional, nonpowered display prop. All names, codes, parts, and support routes on this page are invented for the example.
Keep every part in view until the inventory matches. Do not begin with a missing, cracked, bent, or differently coded piece.
Stop before assembly if a code does not match, a part is missing, an edge feels sharp, a panel is cracked, a foot is bent, or a bolt thread looks damaged. Do not substitute hardware.
Upright groove faces rear: remove the sign panel and shelf, support the upright, remove both long bolts, lift it straight out, rotate it, and repeat steps 4-6. Never twist the upright while it is bolted.
Shelf lip faces down: remove both knobs, lift the shelf straight up, turn the lip upward, reseat both tabs, and reinstall the knobs. Do not pry a tab sideways.
Remove it. Confirm BLT-S is used for the feet and BLT-L for the upright, then realign the holes. Stop and use the support route if the correct bolt still catches or the thread looks damaged.
Move the stand to a known level table. Check that both feet are in their marked positions and sit flush. Stop if either foot or the base is bent; extra tightening is not the repair.
Lift the panel straight out and check that its arrow points up and both clips are intact. Reseat it without twisting. Stop if a clip is cracked or only one clip becomes visible.
Remove the knobs and lift the shelf away. Check that the lip faces up and both tabs align with the lower slots. Do not widen a slot or bend a tab.
Fictional support route: stop work, keep the unit disassembled, and give the workshop lead the kit code P-24, the part code, the step number, and a photo of the problem. Resume only after the workshop lead supplies the matching replacement or written correction. A real manual must replace this route with the manufacturer’s current contact and escalation details.
Finished state: the blue arrow and upright groove face front, the shelf lip faces up, both panel clips are visible, both feet sit flush, all listed fasteners are present, and the stand does not rock on a level table.
