Build Tips

1

Check the piece count on the bag against the parts list before starting — knowing what you have prevents mid-build surprises.

2

Even in small sets, connection order matters. Follow the steps rather than building sections independently.

3

Keep the instruction booklet after building — it's the most reliable reference for disassembly, cleaning, or reassembly after storage.
